I applied through university. The process took 1 week. I interviewed at Jane Street (Hong Kong) in Feb 2025
Interview
There were 5 rounds through the placement cell of IITB. Every round was testing different things, one round was a game theory question, another was time series modelling, one on market making for a complex card game, etc.
Interview questions [1]
Question 1
There was a market making game where 3 sets of 5 cards were to be flipped and there were many power-ups like +10 if there are more than 4 cards of the same color in a set, etc. We had to make a market on the final game value.
