Career Advice Weekly Megathread: Education, Early Career and Hiring/Interview Advice

0 Upvotes

Attention new and aspiring quants! We get a lot of threads about the simple education stuff (which college? which masters?), early career advice (is this a good first job? who should I apply to?), the hiring process, interviews (what are they like? How should I prepare?), online assignments, and timelines for these things, To try to centralize this info a bit better and cut down on this repetitive content we have these weekly megathreads, posted each Monday.

Previous megathreads can be found here.

Please use this thread for all questions about the above topics. Individual posts outside this thread will likely be removed by mods.

Trading Strategies/Alpha I've been running an HFT stat arb for 2 year now. 3+ sharpe.

64 Upvotes

My account was originally suspended by my broker for exceeding their Order-to-Trade Ratio (OTR). Since then, I’ve adjusted the strategy to be more conservative. It's now running smoothly, generating ~50% annualized returns with a 3+ Sharpe ratio.

The estimated capacity for this strategy is around $20M. However, I’m currently bottlenecked by my available capital ($400k) and my broker’s API rate limits.

Does anyone have advice on how to effectively reach out to pod shops or prop trading firms to discuss scaling or seed funding? I’ve tried cold emailing a few, but haven't received any responses yet.

Data Which microstructure metrics have actually survived live trading for you?

9 Upvotes

Ive implemented a fair number of the textbook microstructure metrics while working with raw crypto perp tick data.

The more I compare them, the shorter the list I actually reach for !

If I had to keep only five:

  • Order book imbalance / OFI: still the strongest short-horizon predictor Ive found. Static imbalance and Cont-style OFI aren't the same object, but both seem to contain real information. The problem is that the half-life seems tiny: by the time youve paid fees and accounted for queue position and latency, a nice t-stat doesn't necessarily translate into PnL.
  • Amihud illiquidity. almost embarrassingly simple but I keep failing to replace it with something more sophisticated; I mostly use it as a liquidity or regime variable rather than a trading signal.
  • Effective spread / realized spread Extremely useful for understanding execution quality and adverse selection. I'm much less convinced they belong as features in predictive models, although Id be interested to hear if anyone has had success there.
  • Kyle's lambda I trust the ranking across instruments more than the estimated values themselves. Small implementation choices (sampling interval, trade signing or outlier treatment) seem to move the estimate more than Id like.
  • VPIN : The one Im most sceptical of: I can usually make it identify stressed markets, but so can realised volatility. The Andersen Bondarenko critique feels fairly convincing to me, although I'd be happy to be proven wrong by someone who's used it successfully in production.

For context, this is all on crypto perps, so I wouldnt expect the conclusions to transfer unchanged to equities/ futures.

Im particularly interested in hearing from people who've used these in live systems rather than backtests.

Which measures have actually survived implementation costs for you? Are there any papers from the last decade that genuinely changed your view on the classics?

Bias disclosure!: I build infrastructure that computes these metrics as a living, so Im probably more sympathetic to them than I should be.

Industry Gossip Is Anyone in Equity Stat Arb Making ANY Money???

51 Upvotes

Have spoken to colleagues across multiple pod shops (and a few lower level QR at collaborative shops), it seems that true market-neutral alpha is almost nonexistent this year...? A lot of returns being posted by multi-strats are from discretionary or non-equity quant trading.

It could be that I have a limited sample pool, but I haven't heard of even the usual top dawgs like 2S and Shaw doing well this year purely on equity stat arb. Has this been the experience across the board for everyone? Has equity stat arb this year just turned into 'factor timing'?

Hiring/Interviews Is it possible to join a big trading firm with conviction record?

30 Upvotes

I have a minor conviction record (happened in about 9 years ago, about 2K USD fine paid). It's not related to felony, fraud, or finance-related. It was showing bad behavior due to alcohol intoxication (no drug).

I'm currently working at local trading desk as a researcher/trader but I wanna move to big firms in SG/HK.

AFAIK, there is a background check after the final interview. My above record is all spent so it doesn't appear on my official criminal history document. But not sure whether I should disclose it or not.

Also, I heard that there's a question like "have you ever been convicted in court of law in any country? " when applying for SG EP visa. Some SG lawyers say I don't have to disclose but quite confused about this part.

Does anybody know some cases like my situation? Or should I just stay in my Country..?

Career Advice Looking for Perspective on Interview Conversions

8 Upvotes

Hey everyone,

I'm a QR with around 2–3 years of experience in the job market right now. Lately I've been getting a bit worried about my interview conversion rate and wanted to get a sense of what others have experienced.

So far, I've been submitted to around 18 firms through headhunters. I've heard back from 13: 3 resume rejections, 4 screening-call rejections, and 4 rejections after the first technical round (OA, coding interviews, etc.).

During this recruiting cycle, I had some personal issues going on and wasn't able to devote as much time for interview preps (I've managed to get through maybe around 50 LeetCode problems). Looking back, I think I underestimated how prepared I needed to be for the first technical rounds and assumed I could mostly wing them. Or maybe an ideal candidate should be able to wing these, but more on that later.

I have two questions please, if you could give some advice:

  1. A couple of the technical interviews felt very doable in hindsight, and I'm pretty sure I'd perform much better if I took them today. For firms where I was rejected after the first technical round, is it generally possible to interview again after the cooldown period, or do they usually expect a more substantial career update before considering another interview? And how is that done, if the initial one was done through a recruiter?

  2. It's easy for me to attribute these outcomes to being underprepared, but I'm also trying to evaluate myself honestly. There are obviously people who can perform extremely well in these interviews with minimal preparation. How common is that among successful quant candidates? As someone who's still relatively early in my career, I'm trying to distinguish between "I just need to prepare properly" and "this may not be the best fit for my strengths."
    I guess I'm trying to see if I should also look for other opportunities other than just buy-side QR seats.

General Is polypaths that popular on the street?

3 Upvotes

I intern at a small bank and I found out that bank mainly uses polypaths for managing its billion dollar fixed income portfolio ( MBS, CMBS, ABS). But do people on the street really use third party software for risk and pricing, why not use in-house models given the depth of research papers, books and job experience?

Education Need more advanced books

7 Upvotes

I've been doing quantitative strategy development for some time now and Ive reached the point where Im struggling to find books that actually teach me something new. I already have a solid understanding of the usual topics like IS/Validation/OOS splits WFO, cross-validation, permutation tests, bootstrapping, entropy, regime detection, and the other standard robustness techniques. I recently read Testing and Tuning Market Trading Systems by Timothy Masters but it covered concepts I was already familiar with.

Im looking for books that are genuinely advanced and make you think differently. Perhaps graduate level or even post graduate books on statistics, machine learning, optimization, information theory, econometrics, or anything else that completely changed the way you approach research and model development. And of course it would be great if the book wasnt 10 years old. Need relevance.

Industry Gossip LLMs provided in interviews

58 Upvotes

One of my colleagues mentioned when interviewing at Citadel they provided him with their own LLM he could query during a coding assessment. This was for a technical but non quant role.

I’m curious if people have similar experiences and what people’s thoughts are on this. Personally I think this opens up the scope of potential questions massively, and tests a new skill (prompting proficiency). Will this be the new norm?

Industry Gossip Small Quant firm interview

32 Upvotes

Just got my first ever interview, it’s at a small firm so I have some reservation in terms of scale of the company( AUM, P/L). The people seem to be from other firms that I know are good but the team doesn’t seem to have that prestigious College background so that stuck out to me. Usually when I think quant it’s Phd or from MIT Harvard Princeton or something like that.

Anyway to learn about the firm?

Career Advice For quants who pivoted to data science, what kind of data scientist are you?

31 Upvotes

Essentially, I've been a quant for about 8 years now (first global macro strategies, then algo research at a bulge bracket - worked on pricing and predictive modeling) and want to do something different. I'm just looking for less unpredictability, less "live" day-to-day pressure, and more WFH flexibility, so I'm planning a pivot into data science (I understand I may find these things in other areas of finance but this isn't what I'm asking). I've been applying to data science roles, mostly in tech and fintech but I haven't gotten much traction so I want to understand what DS roles quants are typically competitive for so I can focus my efforts.

For those of you who have successfully transitioned from quant to data science, it would be helpful to know:

- What type of data science role you were able to get and in what industry? (Type ~ Product DS, Applied Scientist. Machine Learning Engineer, Dynamic Pricing DS (Uber, Lyft, Amazon), Consumer Credit Risk/Fraud DS)

- What area of quant finance did you work in prior to the pivot?

- Your assessment of the difficulty of making this jump.

- What gaps to fill to improve odds

I'd appreciate if responses focused on actual examples of those who have or know someone who has made this pivot, as opposed to what is conceptually feasible.

Thanks in advance!

Tools AI use

23 Upvotes

I'm starting a quant research internship at a big hedge fund next month and I am looking for advice on how to best profit from Claude Code, some friends tell me it is widely used in the industry.
I anticipate how fast paced the environment will be and the internal incentives to use AI but how should i use it to not get dumbed down, I want to make the most out of my internship (learn a ton) AND be fast and deliver and I feel like both might be difficult to achieve at the same time.

How do you use Claude at work AND stay relevant ?

Career Advice Opportunity to move to Canada (Toronto or Montréal) - how's the market there for QDs ?

3 Upvotes

Hi again, everyone !

I'm a QD (3 YoE SW, 1 YoE QD) at an investment bank in France, in the pricing department. I'm also the dude who wrote the post about being a fraudulent QD last week, so hi to everyone with whom I've chatted last time.

There's a personal opportunity I'd like to take advantage of in Canada (either Montréal or Toronto), but I'm a bit skittish at the idea of going there and not easily finding a good position. If I do move there, it'll be in the spring/summer of 2027.

A quick search on Linkedin jobs shows a lot of hybrid AI-for-finance positions, but not that many mid-level performance-oriented more "traditional" QD jobs, especially in Montréal.

Do you guys know what the market looks like over there (abundance of offers, background constraints, comp, etc.) ?

Thanks in advance and have a great evening.

Data What will be important in signal research?

2 Upvotes

You hear about firms that have heavily invested in data and deep learning, replacing much of the manual work done in signal research with models learning on raw order book data.

On the flip side, there are microstructure tricks that are discovered due to clever observations by humans that models aren't necessarily picking up on without those priors first being taught to the models.

Going forward,do you think will powerful models, combined with huge amounts of data and the hardware and other infrastructure needed to run experiments largely replace clever human observations? Or will there still be room for the classical, manual feature engineering which has been how much of the trading world has functioned before the recent compute/model revolution.

Industry Gossip Are LLMs reshaping and consolidating the industry ?

4 Upvotes

I work in a top tier trading firm, and it’s going mad for last 2 years. Not only the level of analysis and rhythm increased a lot, but also it seems the management wants to merge all the teams and just keep 4-5 great guys (vs 50 people in total), even if all the teams were profitable. I am surprised how AI makes so PMs so cocky, thinking they can do everything alone now.

I also recently talked to other firms by curiosity and the hiring standard seems to have increased a lot. A firm I passed successfully 5 technical interviews 3 years ago, rejected me on the first round recently (in spite of my skills having clearly improved). Some don’t even know how to hire anymore.

Am I getting outdated and replaced by new generation or is the industry consolidating significantly ? I have a hard time believing you can divide staff by 10. All the firms like RenTec, DESCO, XTX are heavily using AI in a smart way for past decades and still leave room for alpha.

Excluding London, which are the best cities in Europe to build a career?

By "best" i mean the overall balance between net salary, cost of living, commute times, work-life balance and workplace culture.

It would be especially interesting to hear from people who have worked in multiple locations throughout their careers.

Data How are you all pulling normalized LMP + congestion data across ISOs in 2026?

5 Upvotes

Trying to do cross-ISO work (PJM/MISO/ERCOT/CAISO/SPP/NYISO/ISO-NE) and I'm losing my mind reconciling seven different schemas and update cadences - the congestion component especially (NYISO's sign convention alone…). Right now it's a pile of per-ISO scrapers held together with tape. Is everyone just using gridstatus / rolling their own, or is there something that already normalizes all of this? Curious what SPP/MISO historical depth people actually get.

General Best way to deal with 1y garden-leave

66 Upvotes

Hi,

Although I am not looking to move, I answered a few recruiter's email recently, and quickly found out after a brief discussion that, even in the same market, some potential competitors or other firms would be quite reluctant to wait a year for me to join. 1 year is roughly the official amount of time I can be prevented from working for another company (can be lowered depending on circumstances and context).

That made me slightly anxious about the future because one day I will indeed move, I do not plan on retiring at my current company.

What is the feedback in that space and did you all genuinely take all that time off without any guarantee of what your future next position would be ?

Career Advice What do you do when nothing is going wrong?

73 Upvotes

I’ve been on a desk as a QR now for over a year and a half. In that time, I’ve deployed strategies that have gone to production and are doing well within expectation. I’ve build dashboards and reconciliation tools. Everything is going well.

Now I am at a point where I’ve produced enough research to keep the devs and traders happy for the next year or so and I’m bored. I’m wondering what some more experienced QRs do in this situation. I’ve almost exhausted all the meaningful projects just because I’ve managed to automate and speed up parts of the research loop to the point where I can test ideas in day that used to take a month or more.
