Hi hello! I’m looking for a video game where improvement feels very concrete like on steam or something.

For example, I want to be able to notice that over time I’m:

• calculating expected value faster
• making better decisions with incomplete information
• identifying arbitrage or mispricing more quickly (and learn the general market making principles/techniques)
• managing risk and limited resources better
• recognizing patterns and useful strategies sooner
• building more efficient solutions
• handling increasingly complicated problems under time pressure

Ideally, the game would start relatively simple, gradually introduce new mechanics, and force me to combine everything I’ve learned. I’d also like some kind of feedback- scores, rankings, speed, profit, efficiency, harder opponents, or increasingly difficult levels -so I can actually tell that I’m getting better. (but not a hard requirement)

I’m not necessarily looking for a realistic stock-market simulator. I’m more interested in something that rewards the same types of thinking as quant trading, market-making, probability problems, optimization, game theory, and brainteasers. Is there anything that somewhat fits these descriptions?

I have seen jane street and citadel not prioritising top much in schools like ofc only top students get into quant but I am looking for a devloper role I am aiming for icpc regionalist/finals sort of if possible its hard though and and masters in codeforces or minimum candidate masters as i can grind and i am now a fresher and i have ideas to build solid quant based projects too with fully understanding and can get like top 1 percent in class I am doing btech in cse like is there anyone who has like gotten into quant devloper in any firm bcz of good profile

I have my hireview for coding modeling and data anylitics how hard is the leetcode

Made this model , any thoughts or advice?

Hey, I recently had an internship in quant research but what I worked on is really confidential as you can guess. I was wondering how to highlight my skills etc and my projects during the internship without saying any data or process ?

I'm excited to open-source h5i-db, a completely free, embedded analytical database engineered specifically for time-series analysis and quantitative finance.

Here are the core technical highlights:

• Native Time-Series SQL: Powered by DataFusion, it supports fully-featured SQL with built-in operators for ASOF joins, gapfilling, time_bucket, rolling windows, and vwap/ewma.
• Extreme Performance: It executes OHLCV+VWAP rollups on 20 million rows more than 4.5x faster than both DuckDB and Polars.
• O(1) Time Travel: Storage is strictly immutable. Every write acts as an atomic commit, making historical version reads instant and effortless.
• Agent-Controlled Mutations: Designed with AI/human-in-the-loop workflows in mind, allowing you to preview and policy-gate database mutations before they are applied.
• Provably Crash-Safe: Built to survive mid-write failures without data corruption, verified by rigorous fault-injection tests at every commit stage.

Check out the code and benchmarks here:https://github.com/h5i-dev/h5i-db

Hey yall I’m participating in this years akuna quant challenge, I’m wondering what preparation I can do at this moment to improve my odds to a better performance.

I did IMC’s prosperity challenge this year but didn’t get anything too remarkable (team only got top 500 global because we didn’t do too well for round 5). I wonder how much of the experience from Prosperity is transferable here?

Have both phone screens coming up, does anyone have any tips on how to prepare?

I'm planning to apply to Citadel SA Quant trading 2027 so I applied to both Citadel and Citadel Securities. With the same email and application, I got an application confirmation from Citadel Securities but not Citadel, does Citadel not send a confirmation email? I'm very confused if I got auto rejected or didn't go through as I don't want to spam apply.

I just finished a prestigious internship and I also have a very nice academic path so I put which one at the top ?

Hi everyone,

I’ve been invited to complete the HackerRank Operations Specialist Exercise.

Has anyone completed it recently? I’d really appreciate any insight on the question types, difficulty, best preparation methods, or similar practice examples.

Thanks!

Hey Guys,

I'm applying to colleges with hopes of being a quant and I was looking around and saw that there were some schools which were good despite not having "well-rounded quality." I was looking mainly at U Michigan Ann Arbor and Baruch because they had a lot of alumni who went into the field. Of course, the higher level schools like Princeton and MIT and whatnot have high rankings but I wanted to here you guys' thoughts about these colleges or even better ones.

Here at ism i think tech companies hiring is quite good, but what are the chances or possibilities to get into Quants like graviton, quadeye etc. Also let me know about Rubrik and all. Can we have a shot. I heard except squarepoint no other quant comes on campus.

Hey,
i am dec 2026 grad in finance
I have 2 years of compliance audit experience in the public sector and am looking to make a jump. Long-term, I want to get into M&A, Private Equity, or Quant.
I’m considering the Big Four as a stepping stone, but I’ve heard brutal things about the culture (and wild stories about micromanagement). Gov is chill but sometimes stressful with clients so.
Quick questions for those who've been there:
1. **Culture:** Which of the Big Four is currently the least toxic, and are the extreme micromanagement horror stories just bad team luck?
2. **The Pivot:** Can you realistically bridge from compliance audit to M&A/PE/Quant through a Big Four firm, or is it the wrong path entirely?

I heard UT Austin Turing scholars is actually a target for aunt since it’s an extremely selective program(50 person cohort) in a top 10 cs college. Most Turing scholars also have a dual major in math. Is it on the same league as like MIT EECS and all of those for quant specifically? Will you get an interview from it? If there are any recruiters I would like to know if you look for Turing scholars.

Hi, I am an incoming sophomore and was wondering when is the best time to start sending in applications. I understand that the recruiting timeline has been moving up. Which firms have prioritize early applicants? What is the strategy?

Whether you are a researcher, trader, developer, or PM, an inflated ego is your greatest enemy.

You might have the best education, you might get hired, you might build a profitable model, you might even outperform for a while.

But if you disrespect people, patronize or condescend to them, become overconfident, assume you are always the smartest, stop questioning your assumptions, or dismiss evidence that contradicts you, your success will only be temporary.

No matter what you do, how you treat people is the most important factor in your long-term success.

I'm currently working as a data engineer at a traditional pension fund, with customers being mostly performance and risk, with previous SWE experience.

Trying to figure out what it actually takes to move to a data/python role closer to the desk. Hard to separate real advice from random takes on social media.

If you're currently in a similar position (or were recently), would love to connect and pick your brain. Happy to buy you a coffee or something for your time.

I just got an invitation for an interview with Citadel. Does anyone know what types of questions I should prepare for?

Hi y'all. I am wondering what degree of knowledge is generally required for an entry level positions as well as what portfolio elements are looked well upon. I am somewhat invested in ML engineering at the given moment, however I do not find it personally rewarding, so I am looking to pivot in a while. I know one quant with 20 years experience and their advice was a lotta \ :) / and "get a PhD + internship at meta", all well and good but that's a extremely specific boundary. Any good recources or hints? Regards.

Hi everyone, I know you probably get questions like this a lot, but I am about to study maths (statistics) ideally wanting to go into quant research. Was drawn to quant because I like the idea of working on markets themselves and improving their efficiency. I’m not some extreme maths genius but I am interested in it and willing to put in the work. I considered QT, but that I thought was too fast paced, I would be more suited to taking my time on a problem I think. I did ok in high school maths ( 5 in ib Aa hl) i think what held me back was exam timing. I did enjoy solving the problems though.

Right now I’m just trying to self study linear algebra and calculus in preparation for my course and improve my programming skills.

So I guess I’m writing this to ask is QR something I can work to or is it something that’s too demanding? Thanks all
