Is a quant developer interview just a normal coding interview?

No. The algorithms bar is comparable, but questions are often wrapped in quantitative content - simulating a process, computing an expectation efficiently, or reasoning about numerical stability - and both the implementation and the reasoning are graded.

How much probability do quant developers need?

More than a general software role. You will not be asked to derive research-level results, but you should be fluent in expectation, variance, distributions and basic stochastic processes, because they appear throughout the systems you would build.

Quant Developer Interview Questions

Quant developer interviews combine data structures and algorithms with the numerical and probabilistic reasoning that trading systems demand - clean implementation under real constraints.

Expect algorithms and data structures at a level comparable to a strong software interview, but frequently blended with quantitative content: simulate a random process efficiently, compute an expectation without blowing up numerically, or reason about the complexity of a pricing routine.

Systems questions appear too - latency, concurrency and correctness under load - because the code runs against live markets. Probability and statistics remain in scope even for pure engineering tracks, since the domain is quantitative.
