An alarming number of people don't understand that LLMs work via purely stochastic processes, so I'm happy to see in-depth pieces like this. I'm looking for a job and maybe this is why it's so hard to get a callback these days: resumes are just dumped in some LLM black hole and no one really knows how it works. The author says:

> temperature 0.1 — low, supposedly nudging the model toward deterministic outputs

This is not correct (and is briefly touched on later in the piece when he sets temperature to 0), temperature is not some kind of "deterministic" switch, but rather it affects the sampling distribution (which becomes more "spiky"—but is still very much a distribution).

And this + the tendency for AI to "prefer" AI produced code + some other AI biased is why *this is most likely highly illegal to use in the EU due to violating anti discrimination laws in multiple ways.

To be clear:

- randomly filtering "too many" resumes is pretty much allowed (I think)

- but must be actual random independent of the resume (and can be in multiple layers, i.e. random filter > pre-select > random filter > select)

- this isn't the case for AI as the random aspect isn't done as the random aspect is not independent of the actual resume evaluation

- in general you can't make sure the AI doesn't apply systematic biases, and there is high indication that it does do so

- for humans you can train them and order them to ignore their biases, this won't work reliable either _but now you delegated the responsibility of illegal biases to the hiring personal violating the order_. But for AI usage you are responsibility no matter what you tell it. Lastly you can technically "show/proof" a specific used AI is highly biased in a specific contexts, which for human employees is technical possible but practical not really practical. So this moves "specific mostly deniable" cases, into "systematic proven bias" teritory. Or in other word legal risk goes from "limited/no issue" to "people can systematically f-you over if they know you use AI for hiring".

At this point we might as well adopt that joke where you blindly throw away half the resumes because you don't want to hire unlucky people.

> I fail 65% of the time. Same exact resume, different luck.

As someone who’s run hiring pipelines for technical roles in the past few years, that’s actually a fantastic number. I objectively hate saying that, but it’s true.

35% chance of elevating a technical individual to the next stage with no effort? I’ve seen as many as 100+ applicants an hour even when including a domain specific screener question. That’s 35 “screened” applicants in an hour. Were valid candidates screened out? Yes. Does you still have a candidate pool 35x larger than you need? Unfortunately, also yes.

The volume of applicants is SO HIGH such that your chances of getting moved to the next stage are actually markedly worse if AI isn’t involved. If you didn’t apply immediately (using an AI bot) there’s 50+ people ahead of you, and an exhausted technical leader if they ever make it to your resume.

Referral bonuses exist for a reason.

I think what's more worrying to me (if other systems work like this ATS) is that it seems to judge based on a bunch of factors that will probably disqualify a ton of decent to good participants.

For example, 65 points are given for a mix of personal projects and open source contributions. Which is great if your one and only interest is in tech, and you don't have a family, dependents or a second/third job. If you have any of those other things, well the odds seem like they're incredibly stacked against you.

And it makes me wonder how many of these systems are stacked in favour of wealthy people with a near special interest level of obsession with tech and no worries outside of going to college/working a single job in their industry of choice.

This word (determinism) has a magical effect of warping any online posts it touches. Once you hear it you can almost guarantee it's going to be misguided. At least this time it's actual determinism (same input = same output), not arbitrary unrelated things.

Determinism matters for reproducibility, but do you really want these outputs to be reproducible in this particular case? Making LLM outputs deterministic is relatively trivial, you have to use batch-invariant kernels (if you use batching) and either set the temperature to 0 (don't do that, randomized sampling is here for a reason) or fix the seed (better). It's readily available in a few systems. But this won't make the result more useful, it will just obscure the fact that the agent is genuinely not sure about it - look at the range of the scores it gives! It still won't predict anything but the score will stay the same each time. Do you really want that?

What happens here is they're supplying too little information (just a resume, which is almost at the noise level) and expecting a reply with too broad implications. This is a basic design mistake regardless of whether it uses LLMs. All surveys, tests, laws, and voting systems are extremely sensitive to framing because they work off too little information. But they also don't exist in vacuum, unlike this thing.

I ran the ATS myself and had a similarly quirky experience. I was in the 70s because it couldn't find my GitHub profile, and then it didn't like some of the popular Ruby libraries I'm the author of.

After a few runs it picked things up appropriately. I always got dinged on formal education though.

This stuff is gross.

It's always amazed me that a tech company will pay $300,000+ for a good engineer, because talent is so hard hard to find... meanwhile their recruiter operates unsupported, has a very different idea about what good looks like. Their ATS black-holes >50% the resumes because it's filtering heuristics are garbage because recruiting selected the ATS system because it has a google Gmail integration or something, and the ATS's filtering technology was not reviewed by anyone in the engineering or data teams.

> The default model is gemma3:4b

That’s a tiny model. No LLM is going to be a perfect and repeatable judge, but a tiny 4B model is like plugging an RNG into this system.

This whole exercise feels like someone vibe coded an ATS and got it to the point where the tests were passing because they decided they should have an open source ATS project.

Feels like "I Don't Hire Unlucky People" all over again, but with extra tokenmaxxing steps.

This is the new AI reality everyone around is wanting: a nondeterministic computing.

There is another name for it: a waste of electricity.

But wait, not waste! Consumers paid for it fully, with nice profit margins.

You and me, paid.

Try using google flights, or booking.com: the prices shown in search results list are frequently significantly different from those in a single result. It's a nondeterministic compute when it's easy to spot it. But it's not always that easy.

It's all sad, to be honest.

I tried this with my CV, and it somehow scored me bonus points for GSoC!

   BONUS POINTS: 5.0
  ------------------------------
     Google Summer of Code (GSoC) participation: +5

I'm a little confused, is this an ATS system that anyone actually uses? If not, I'm not sure how it's better than just asking ChatGPT to score your resume out of 100. Why would you want to optimize your resume for a system no one is using to score it?

This insanity only exists because the tech industry is standard-less. No formal education needed, no formal training requirement, no apprenticeship, no software building code, no professional organization. Resumes have never been a good predictor of success - and why would they be?? Even if they're truthful and it's "impressive looking", that doesn't give you any assurance of knowledge, of who they learned under, what they learned, that they passed some minimum criteria. We might as well be rolling dice. So why not an LLM that randomly assigns scores?

Oh ok. So I'll just have to apply 4-5 times to every job to be sure I'm considered. Sounds like a good equilibrium!

If I know the truth value of p and I also know p=>q, then an LLM would be able to deduce the truth value of q - even if the statements aren’t exactly in this form. Generally, LLMs are good with logical inference.

But logical inference itself is limited. You still have to find out if p is true or not - the ground truth.

How do you find that? You would be able to define in the prompt that if resume has p, infer q and do this. But determining the truth value of p is something LLM cannot do.

It’s not a limitation of the LLM. It’s the limitation of logic itself. You take 10 humans and give them the resumes with the same rubrics as the LLM. You’ll get a similar range of scores because everyone would assign different values.

The issue is not in logical inference. It’s in determining the value of p, which takes much more than logic. And current LLMs are limited to being logical.

Yep, any day now AI is going to be so good we'll never need to think again. What's that, it's just a really expensive random number generator?

It's fair to call out issues with the tool. But I think for individuals searching for jobs, using LLMs as the scapegoat for why it's hard to find a role is not terribly helpful.

In my experience, cold-applying has always worked essentially as a black hole, and LLMs haven't changed that much. The reality is that alternative avenues are always necessary to get the job you want. That could be a third-party recruiter; reaching out to a hiring manager on LinkedIn; or using your network to get referrals. Those continue to work whether the company is using a bone-headed tool like this or not.

Hiring and job search has been so hard and AI has amplified the existing problems instead of solving any.

From `resume_evaluation_system_message.jinja`

> *SCORES MUST NEVER DEPEND ON THE FOLLOWING FACTORS:*

> - College, university, or educational institution name

> - CGPA, GPA, or academic grades

I don't understand why they would omit these factors from the evaluation.

It's funny that even after all these years and all this money invested in technology, we still haven't come up with anything better than word-of-mouth for hiring great people. Many serial founders have said that, despite the most stringent interview processes and the most sophisticated filtering pipelines, they still have a higher hit rate with people they've worked with in the past.

This isn't to diminish the whispernet. Rather, it shows just how many important signals cannot be quantized.

> Sometimes my projects “lack architectural complexity”

Well done you! It is difficult to avoid architectural complexity, but imho well worth it.

The list of "bonus" criteria and how they come about makes me feel sick.

I am not currently looking for employment, nor am I currently particularly worried about future prospects if I was suddenly in the position of looking for employment.

But if I ended up in a position with nothing to lean on but scattering my CV everywhere, well…

A lot of my major contributions are littered across the internet, private, or even just verbal/consultancy. They're things I did for free, in my spare time.

I also avoid GitHub. If you just look at my GitHub page for extra context, you would likely miss that delivering that very GitHub page likely involved a few bits of code I wrote.

Now, I could do a better job of trying to document this stuff, so it could be easier to find… But also I can't quite imagine how that would work.

The takeaway from this for me is that, using an LLM to score anything takes multiple (maybe even many) runs and the result you’ll get is, at best, a sane-ish distribution.

Which sort of sounds workable until you scale it up to larger datasets, where at some point compute/time/energy costs will render it non-viable.

I am sure there’s some reasonable rule of thumb estimation on distribution that could be applied based off fewer runs per data artifact, but you’re always going to be trading off against confidence by doing this.

Beyond this, I’d bet that almost no implemented systems that use LLMs for scoring, ranking, or decision making use such a multi-run approach. Partly because people don’t understand their behaviour is stochastic, perhaps because a lot of people without a background in statistics don’t understand what stochastic actually means, and no doubt partly because of budget concerns: if you have to ask an LLM to do the same thing 10, 50, 100 times to get a sufficiently good result, then the cost saving argument is either weakened or completely destroyed.

There is at least one more aspect worth considering in the specific case of resumes/CVs: is the inconsistency of scoring by LLM worse than the inconsistency of scoring by a human following a similar process?

Because the reality is that, even for an experienced recruiter, reviewing hundreds or thousands of resumes or CVs gets pretty fatiguing. People get hungry, bored, tired, restless, irritable, etc.

That inevitably leads to inconsistencies creeping in, so there’s always an element of “luck” (or, perhaps better, uncertainty) as to whether your resume/CV passes screening.

So is that inconsistency better or worse with LLM screening? I don’t know. But, at least, if it’s not worse maybe it doesn’t matter for this specific use case. And if it’s notably better then maybe it’s raised the bar on what “good enough” screening looks like?

(And I’m sure other use cases warrant similar, “does it matter?”, questions, with the answers no doubt landing differently.)

Count to three, no more, no less. Four shalt thou not count, neither count thou two—excepting that thou then proceed to three. Five is right out.

The blog post itself has pretty a pretty strong un-copy-edited ChatGPT vibes.

What does ATS mean? Neither github repo nor article explain that.

Hmm...six runs with gemma3:12b.

- Varies from 102.0/100 to 100.0/100

- Missed lots of OSS work

- Misinterprets GSoC work (Thinks projects I started that were contributed to in GSoC implies that I received a GSoC stipends)

- Areas for improvement seem to vary inconsistently (There's not enough project detail to there's too much project detail)

I still don't make company's cut offs ¯\_(ツ)_/¯

A better way to reformulate this problem is for the LLM to be tasked with making a _comparative_ judgement between two CVs. This should prove much more reliable, especially if you give it a third “too close to call” option. You can also ask for clear justifications of preference.

What is an ATS?

Why is it so hard to write out an acronym once...

He tried with a tiny model (gemma3:4b), got a range from 66 to 99. Then tried again with a small model (gemini 3.1 flash lite), the range was 48 to 64. Would a frontier model be more consistent? Perhaps this tool was optimized for more capable models?

Disregarding the fact that this thing is completely broken, its grading rubric is ridiculous to begin with (as was mentioned in the article itself, but I must reiterate how completely stupid this is):

> 35 points for open source contributions

> 30 for personal projects

I don't contribute to open source or have personal projects because I don't spend my free time doing what I do 40 hours a week to make a living. My 15 years of work experience is worth a maximum of 25%, so any company using this idiotic system would pass on me immediately. Open source and personal projects are fine, but in no sane world are they worth 65% of a resume's score.

> An LLM is called six times to extract structured information

Well, I think I found your problem

I see mention of PDFs both in the article as well as the repo...But i think over the decades that I've been working and applied for roles - almost exclusively in corporate america...I've only been asked for a PDF once! Every other time, everyone wants a Word doc (.doc/.docx). So...is there now some growing HR groups who are asking for PDFs instead? Or, is that if someone asked you for a PDF instead of a Word doc, then that's a signal that said HR groups are employing some sort of agentic review of one's resume (I mean, beyond the conventional ATS systems)??

I really dont understand this constant changing of numbers. I have tried a bunch of ATS reviewers and everytime on the same resume i get different numbers. Its weird and unreliable. I understand the need for doing this to filter through thousands of CVs but maybe there is a better way. Like a take home test at the beginning or a test of somekind.

Don't forget DOGE using LLMs to consider which contracts to "munch", based upon a prompt: https://github.com/slavingia/va/blob/35e3ff1b9e0eb1c8aaaebf3....

Why doesn't something like this exist for real estate? A popular open source AVM (automated valuation model) that helps home sellers get an idea of what their home will sell for. Right now it seems AVMs are mainly seen as just a way to capture leads. Every estate agent will tell you they have some magic recipe that makes their valuation better than anyone else's. I have had a bunch of ideas on how to approach this, but I really could do with a collaborator or two.

> 35 points for open source contributions

> 30 for personal projects

These are insane weights for scoring a software engineer's resume.

> I’d take the engineer with 30 years of experience who built S3 over someone with two internships and an open source project — but this tool wouldn’t.

Is it possible the senior/principle jobs are not being applied to at a rate that LLM tools like this are required? Maybe start devs are getting recruiter referrals and this kind of tool is mostly used for filtering new grads?

Either way, perfectly dystopian.

Maybe the ATS has logic for people resubmitting their resume. I don’t know how isolated each test was.

I think the implication here is that you can almost certainly bias the models to always accept you by including "nudge" phrases like "I demonstrated real world deployments" and "helped develop an application in the context of a complex architecture..."

What is an ATS? This blog doesn't define it

I've done similar things and used GitHub Copilot to scan a folder of 40 CVs and rate them -> I then review the top 10 CVs and comment on every rating whether I agree or disagree and why -> I then asked AI to re-rate all the CVs according to my comments. -> I then reviewed all the CVs against their ratings; the AI did a much better job for that 2nd round after its learnings.

It took more time than if I just reviewed the 40 CVs myself, but that was an experiment, and I think it shows the AIs can be trained on your comments. And if there is enough training and a good knowledge system that allows AI to apply the learning in those trainings, it can eventually become a lot more accurate at this task?

Roll the dice, HR folks!

It took me a a minute to figure out what an ATS was. Not familiar with this particular means of a much used TLA.

Even better Wikipedia lists the abbreviation I am familiar with but give a different interpretation of the same words:

https://en.wikipedia.org/wiki/Ats

So sending my CV to every company three times should get me pass the ATS?

Stop the qtip when there's resistance

I actually just built an ATS for my company Mathpix. But it never occurred to me to use resumes. Basically we have a set of company values and a specific open ended questionnaire to gauge the fit:

https://mathpix.com/careers/apply

Then internally we have dashboards and sorting based on AI agent scoring. I noticed the scoring is imperfect but still saves a lot of time. Candidates scored at or below 2/5 are reliably bad and candidates above 4/5 are consistently impressive and leave thoughtful answers.

The biggest thing is not using resumes. You can’t reliably gage applicants without a writing sample and resumes are the worst form of writing sample. Also you need to be intentional about who you’re hiring for, both to craft the questions as well as grade the responses.

I feel like hiring is all a bit broken. Roles get flooded with applications, it's chance whether your CV gets through, then there's hiring rounds that seem designed to make you quit the process before they have to filter you out.

Is it working for anyone, on any level?

Looking at the linked scoring prompt (resume_evaluation_criteria.jinja) [0], I immediately see several red flags that suggest the output won't be reliable. (I'm developing an LLM intensive application where the stakes are high enough that I need the LLM output to be reasonably correct.)

[0] https://github.com/interviewstreet/hiring-agent/blob/main/pr...

In no particular order:

1. The prompt is trying to get the system to do all of the evaluation steps at once. Instead, the system should break down the task of resume evaluation into its subcomponents and have separate prompts for each component. Like "evaluating open source contributions" should be its own task. Same with "assessing the complexity of software projects on the resume." Fwiw, each of the tasks contained within the prompt is woefully underspecified.

2. The prompt leaves spreads of ~10 points up to the LLM, when it's doubtful that humans are that well calibrated. Take for example:

  > SCORING CRITERIA Open Source (0-35 points) 
  HIGH SCORES (25-35 points):
   - Contributions to popular open source projects (1000+ stars)
   - Significant contributions to well-known projects
   - Google Summer of Code (GSoC) participation
   - Substantial community involvement

3. The authors of this prompt have left an incredible number of judgement calls up to the LLM, when that's the very thing you want to minimize. Using the same example as above...

- Are all contributions to open source projects with 1000+ stars equal?

- What counts as a "significant contribution"? Doesn't that imply that the LLM has to know or read through all of the commits in like the last ~6 months at minimum for the project to understand what the given contribution meant to the project? That itself isn't impossible with tool usage, but again, that'd be a separate task.

- What on earth counts as "Substantial community involvement"? Why didn't the prompt authors define this, or at least give a few examples?

Honestly at this point maybe someone should build a tool that scans prompts for adjectives...

4. This sort of thing is just asking for trouble:

  > SCORES MUST NEVER DEPEND ON:
   Candidate's name, gender, or personal demographic information

5. Obviously this one depends on the LLM in question, but instead of writing things like:

  > DO NOT RETURN A RESUME SUMMARY. RETURN ONLY THE SCORING EVALUATION IN THE SPECIFIED JSON FORMAT. Analyze the following resume and provide a JSON response with this EXACT structure (all fields are required):...

6. One major thing that's not in the prompt is anything about traceability. This system should be designed so that humans can review the logs and make sure this is working as intended.

7. Another thing that is missing in the file is what I'll call evidence of a theory of coding / coder quality. Most of the examples are designed to have the LLM assess proxies for code quality, not code quality itself. Surely both should be taken into account?

I'm not an expert at evaluating coders. But two pretty basic LLM-answerable thing I would ask is: How well do a candidate's 5 most recent commit messages match the contents of those commits? Do the claimed technical skills on the resume match their GitHub code? (i.e., if they say they know R, is there any evidence of that on their GitHub?)

8. The prompt also seems unaware of what it's asking the LLM to do:

  > LIVE DEMO BONUS: Projects with working live demos should receive 10-20% higher scores

This reminds me of my former CTO. He would take bunch of CVs and randomly throw some of them in a bin. He didn’t want to work with “unlucky” people.

>If your company’s cutoff sits at 85, I fail 65% of the time. Same exact resume, different luck.

Your resume's reception is always affected by random factors, only now you are able to test, debug and technically critique the randomness.

ATS resume usually check the keywords, and formatting your spacing and give score accordingly. As If someone is following some reference of the format. It can depend might he will be getting low scores.

Many em dashes and a "This is not, it is…" later, I think this article would have been a much better critic if it didn't use a LLM to (re)write some parts of it.

I wonder how is this even legal? The only useful job the HR departments are ever required to do - they decide to automate it? Aside from being a daycare for adults, what exactly does HR accomplish? It's clearly NOT on the side of employees, but this seems like they're clearly NOT on the side of employers, either.

While resume's are being filtered left and right, they just make TikTok's on company's dime [1]. What a sad state of affairs.

[1] https://www.youtube.com/shorts/wSug80Vg5JU

With such kind of ATS systems, is it still a thing to optimize for a one page resume that is easy for a human reviewer to scan, or just include enough buzzwords and external links to try and please the LLM?

Did anyone try to prompt hack this setup?

I was inspired by this. I made a Claude skill to take my resume and compare it to any job description to point out viability and gaps. Pretty cool skill. I'll post it somewhere.

This could be used as a good way to self-evaluate one's current position from the company's point of view. you would tweak prompts and guidelines that are expected from the company and see how you score

This seems like extremely illegal in Europe.

This is just the 'LLM judge', very badly implemented without any scientific prudence. What a joke. To be terse: you cannot rely on LLMs to provide standardized scores against arbitrary criteria. To get close to 'reliable' you would need highly tested rubrics, grounded in human decision-making, and you'd need to avoid all the measurement biases these things are riddled with... positional/order effects, anchoring on whatever numbers you stuffed into your own prompt, scale-format sensitivity (a 1–5 and an A–E scale give different answers for the same input), holistic-vs-isolated context effects, and lovely examples like where adding a "be unbiased" instruction makes it more biased. I've studied this at length. You cannot even _begin_ to approach this problem seriously without held-out validation, inter-rater agreement, and ground truth. This repo is just quagmire of wishful vibes with random numbers littered throughout.

"A computer can never be held accountable, therefore a computer must never make a management decision."

It seems like the design is flawed, probably because the scoring structure and conditions are wrong. And originally, due to the nature of LLMs, even if the input is unstructured, when you design something like a RAG system, you usually need to create a verifiable evidence table. Even with that, the scores are still probabilistic by nature, but at least they stay within an error distribution that I can verify. But it doesn't seem like there's any such evaluation criteria here.

Typically, retrieval should be tied to evaluation metrics, evidence should be linked to scores, and you also need to account for parsing errors.

But personally, I'm weak to these kinds of ATS systems (ugly appearance, non-native English speaker, didn't go to a good university), so if this kind of filtering existed, I probably would have never had a job in my entire life. Come to think of it, even now I don't have a proper job—I just bid on projects at the lowest price and implement them. So maybe it doesn't really matter whether such a system exists or not

So that's where the Windows XP file copy dialog author now works.

The most concerning thing here is the temperature problem. If your harness isn't providing deterministic output at a temperature setting of 0.0, it is broken.

> An LLM is called

Hooray for incidental non-determinism.

never understood how can people think an .md file can actually evaluate a human being.

I'm from genx. This has been a serious issue in the tech industry for decades even before AI somehow made it worse. The real problem is resumes themselves. It's an outdated format that was originally designed for completely different industries that just doesn't work with ours. And this is a great example of what I'm talking about:

The scoring is out of 100, with up to 20 bonus points on top:

35 points for open source contributions

30 for personal projects

25 for work experience

10 for technical skills

Up to 20 bonus points for startup experience, a portfolio site, a technical blog, etc.

All the AI is doing is trying to sus out the candidates portfolio which is really what we should be submitting when we apply for a position instead of being forced to somehow condense it to a set of BS business-speak bullet points. Especially when employers are now deploying AI systems just to figure out what's in a candidate's portfolio to begin with.

When all you have is a hammer every problem is a nail. The process itself is broken. We need to kill the outdated concept of resumes before it kills the industry.

"If your company’s cutoff sits at 85, I fail 65% of the time. Same exact resume, different luck."

Sounds like they have replicated the existing recruitment process

Are many people using HackerRank ATS ?

I’ve always assumed any LLM output that was some type of rating or score was bullshit. Unless the LLM writes a Python script to calculate the score (and even then…) then the score it outputs is just the next most likely token, taking into account temperature and what not.

You see a lot of frameworks for things like spec-driven development make use of scoring how good the spec/design/plan is and it’s like, uhhh…

They forgot to add "masterpiece" /s https://www.youtube.com/watch?v=mcYl70vq_Ns

https://github.com/interviewstreet/hiring-agent/blob/main/pr...

Ah... The AI learned the old HR trick: take 50% of resumes and throw them out without looking. Rationale: "we don't need unlucky losers".

I cope by telling myself that I probably wouldn't want to work for a company that used an LLM to filter my resume out.

The true test of HackerRank is can you setup a system that combines a document editing / paraphrasing LLM with gradient descent on the HackerRank LLM to turn your arbitrary resume into a reliable 120 out of 100.

One of the weird properties of other people using LLMs is the potential of having oracle access to your opponent. Even if you don't have their exact LLM a good guess at it may be a better model of the opponent than you ever had before.

It's a good analysis but the AI slop writing makes me not trust you've reviewed this and I'm unable to finish or subscribe. I'm sure you're a great blogger but this is holding it back!

Lol next time I’ll just apply with 4 accounts and maybe get in once.

I applied to Posthog twice, a couple weeks apart, and was rejected both times at 1:06am on Monday, exactly. So they are obviously using this sort of thing. Just thought I'd name and shame where I can.

I see.

> LLM is called six times to extract structured information

Followed by

> The default model is gemma3:4b, running at temperature 0.1 — low, supposedly nudging the model toward deterministic outputs.

This is exactly why hiring is even more broken: Because the people looking for candidates are also just as unqualified if not, more.

Using much weaker LLMs to replace the person in charge of the final judgement call is the wrong solution as this is a plain old social problem.

Even if you wanted to use LLMs for this case, the default configuration, model choice is laughably flawed. This LLM can’t be trusted as it doesn’t even know what it is reading.

The correct solution is either advanced OCR with keyword ranking with a basic filter or a far stronger LLM that excels at document / vision parsing benchmarks with an experienced person making the final judgement call in case the technology misses a critical detail.

Rather than using this less accurate one that hallucinates out its decision depending on a dice roll.

This actually makes a lot of sense, it's testing the luck of the candidate through the rng feeding the LLM. You wouldn't want to hire unlucky employees after all! Hiring managers of the past would solve this by throwing every second resume in the trash, now this is a built in feature of ATS.

So many people are willing to participate in this kind of robotic practices in human employment makes me think that many are starting to consider that this is as unavoidable as global warming and rather play along, adapts their career (life) to it, sculpture it towards a specific look, doing things that will give them point on some arbitrary test run. Which I feel being dangerous, leading to superficial minded workforce, not those good in something, including judgement of a problem and solution. But good at manipulation.

Speculative thought only, of course.

Boooo you whores

I guess at least HR doesn’t have to read 1,000 resumes. Heck, to be frank, could they make sense of the first 10 resumes?

I have a love hate relationship with ATS

this is why i dont feel sorry for working 3 remote jobs

this will get patched, as in I'll optimize my resume for this and so will many other people that any edge disintegrates

“The demands of ritual are always stronger than those of reason.”

There's a whole lotta analysis and math and bar charts.

But the big question I want to know is "Why did I score that?" And these slop machines absolutely cannot explain anything. That's the root problem with LLMs as a whole. There is no way to describe WHY an llm makes a decision.

Was it because they are a woman? Does the woman's name have more pregnancies than other names? Was it because their job history make the person older (over 40)? Is the person black or black name? Is the name or address attributed to higher criminal tendencies?

But no, you font get to know ANY of that. Slop machine says 66/100 , if you're lucky to even get a number. Usually its a 30 second rejection, or rejection at GMT 0:00 when the batch is processed and you summarily failed.

>You might as well throw out half the resumes and tell the the applicants you don’t fuck with bad luck.

Hmm, well, maybe a bit with a nuance of elite class structure reproduction (that doesn’t prevent a few transclass to showcase in case anyone critic the perfect meritocracy at run), that’s basically what people get, so crude truth but truth nonetheless.

Oh don’t take it personally. Your own bespoke hand-tailored process of course is different, it does give the opportunity to everyone to reach the most accomplished version of themselves beyond what they ever dare to dream.

It won’t help though with the systematic failure of aiming to provide an accessible path to flourish for everyone and letting no one behind.

Again, this is no fault of any specific player, but as long as a majority feel compelled to move within the frame of the game with few winners that merit all they got in contrast to large stock of inept losers, the outcomes are no wonder.

HackerRank CTO & author of this repo here

There's no better feeling than building something open source and watching it take off. Nine months ago, I built a simple hiring agent to solve one very real problem.

Things it is not: It's not an ATS. We don't use it to screen our open roles. Our customers don't use it either.

Here's what it is: Every year at HackerRank, we get 50,000 to 60,000 intern applications. No human can read that many resumes well. So I built something to rank them, helping me decide which resumes to read first.

[This was before we built AI Interviewer (Chakra) to automate the first round of interviews, so candidates are no longer rejected based on their resumes alone.]

Two things worth clarifying since I've seen them come up in this thread:

The default model is gemma3:4b because it's what runs locally on most laptops - no cloud API needed. Actual resumes are evaluated using a top Gemini model. The repo ships with a demo config, not the production one.

The cutoff score was set very low — the system was designed to rank resumes, not reject them. Only resumes at the very bottom of the distribution were filtered out. The vast majority passed through to human review, where the real decisions were made.

Over the last week, it's taken on a life of its own. People are cloning it, running their own resumes through it, opening issues, sending PRs.

I contributed to open source a lot in college. Somewhere along the way, I drifted away from it. This week reminded me how good that feeling is. This thread has also given me more ideas than I expected. The critiques here are sharp and I'm already thinking about how to act on them. Improvements are coming.
