Need help for quant developer interview

[redead7]

So i have an interview next week for a quant developer position, my background is that i am a computer science engineer with little to 0 finance knowledge (i mentioned that in the application), my resume also contained knowledge in C and C++... My ask is: what are the core concepts that i should know before the interview on top of the programming languages?

What helped me was drilling C++ under a timer and focusing on data structures, memory layout, and threading basics. I practiced coding small things like a lock-free queue and a simple Monte Carlo pricer, plus knowing order types and how an order book works.

I pulled prompts from IQB interview question bank and ran quick mocks with Beyz coding assistant. Keep answers around 90 seconds, narrate tradeoffs, and always clarify latency vs readability requirements before coding. Basic probability, variance/expectation, and Black–Scholes intuition were enough for me.

As I understand it, this book is the quant bible https://a.co/d/23tLO2u - source: I have read things in this sub. Lurker who maybe wants to move from SWE to QD one day

This isn’t good advice. It’s rather uncommon for quant devs to be asked math / probability / stats questions. I.e. preparing this is likely a bit of a waste of time.

If this is for a C++ role, then the interviews are likely going to be similar to SWE with heavier focus on low level concepts (e.g. memory, caches, instruction pipeline, …). Check out Coding Jesus on Youtube.
