Quant and trading interview prep with traders who got the offer

Quant and trading interviews test how you reason about numbers and uncertainty in real time. Expect mental maths, probability puzzles and sometimes a market making game. The questions are hard on purpose. Interviewers care more about how you think out loud than whether you get every answer right.

What the process usually looks like

  1. 1Online testsTimed numerical and logic tests, sometimes a coding challenge.
  2. 2Phone or video interviewsMental maths, probability and brainteasers, solved while explaining your thinking.
  3. 3Final roundHarder problems, trading games and conversations with the team.

Every firm runs its own process and they change from year to year. Ask your coach what it looked like when they went through it.

What interviewers look for

  • Quick and accurate mental arithmetic
  • Clear reasoning about probability and expected value
  • Thinking out loud and changing course when you spot a mistake
  • Sensible decisions under uncertainty
How a coach helps. A coach who passed can give you problems at the right level of difficulty, run a mock trading game and show you how to talk through your reasoning so interviewers can follow it.

Quant interview questions people ask

Do I need a maths degree?

Not always. Strong quantitative thinking matters more than the name of your degree. Practise until probability and mental maths feel natural.

What if I get stuck on a question?

Say what you know, try a simpler version and keep talking. Interviewers often give hints. A mock interview helps you get used to being stuck without freezing.
