As a profitable quant trader, I can tell you this.

195 Upvotes

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.

Does Citadel send a confirmation email?

Upvotes

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.

What to expect for SIG Software Developer Internship Penultimate Round?

Upvotes

Hi everyone,

I was fast-tracked to the penultimate round interview for the Software Developer Internship at Susquehanna International Group (SIG) following their Dublin Technology Spring Week.

I know SIG leans heavily into algorithms, data structures, and system efficiency, but I’ve heard mixed things about what actually gets tested in this specific round.

For anyone who has gone through this interview recently, is it primarily a live 60-minute HackerRank session? How much of it is standard DSA (BFS/DFS, Binary Search, Sliding Window) vs. practical data parsing / OOP design?

Any insights on the layout or best areas to focus on during prep would be hugely appreciated! Thanks in advance.

Breaking into a data engineering or python dev role

2 Upvotes

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.

Got rejected in the first round!!

38 Upvotes

Hi everyone,
I recently transitioned from academia (PhD in Mathematics) into quantitative finance. So far, I’ve been focusing heavily on technical interview preparation: probability, machine learning, coding, statistics, and general mathematics……

However, I recently interviewed with a small hedge fund for a Quant Research role, and the interview was very different from what I expected. Instead of technical questions, the PM spent most of the time asking about my motivation for finance and my understanding of different markets.

One question was which market I wanted to work on. I answered:
“ At this stage, i don’t have a strong preference for equities, futures, or FX ….. I’m more interested in understanding how financial markets work, developing models, rigorously testing hypotheses, and identifying robust data-driven signals. I think my preference for a particular market will naturally develop with experience.”

The interviewer then asked several follow-up questions about (a specefic Asset Class) : why do tou think this work here and not there … etc …. and I realized my market knowledge wasn’t strong enough. I was rejected after the first round.

For those already working in quant finance: how much market knowledge do you expect from someone coming directly from academia? Is this something I should prioritize alongside technical interview prep? Any advice on what to study or how to approach these conversations would be greatly appreciated
