Basically on my previous work experience, research and trading experience, no technical questions. They finally decided to move forward with more senior candidates with 5 or more YOE. (I only have 2).
It was good . The questions were hard but really insightful . The employees were helpful and gave hints during the interviews if you get stuck on a question . The online screening tests are difficult .
Interview questions [1]
Question 1
One question was on markov chains and another on game theory.
3 rounds of interview covering CP, puzzles and some basic statistics and probability
Great experience, puzzles were quite original, CP problems were relatively harder compared to other companies around (1900-2100 in terms of CF difficulty)
