Interview questions [1]
Question 1
Can you describe a time when you faced a significant challenge and how you overcame it?
A difficult interview. Did not encounter question in Leetcode/my own practise, had to think outside the box to solve it. Interviewer got straight to the point, no behavioral questions, so be prepared.

Question 1
Solve this question, walk me through your thinking.
Some brain teasers and probability problems that are variations of commonly seen quant interview problems. Require smart reacting rather than very high level maths or finance knowledge. Friendly interviewers, active involvement.
The interview process involved multiple rounds, starting with a phone screen covering probability, brain teasers, and market-related questions. This was followed by a technical assessment focused on programming and mathematical problem-solving. The final round included onsite interviews with case studies, logic puzzles, and discussions on trading strategies. The process emphasized clear thinking, structured problem-solving, and strong quantitative skills.
