Screening, then hacker rank coding questions and usual optiver 5 round online assessment. coding questions consisted of 1 object oriented question and 2 backtesting and trading questions, involving calculating p and l and sharpe ratio
Interview questions [1]
Question 1
backtest trading strategy, compute p and l and sharpe ratio
Passed Multiple Rounds.
First was a long OA with coding and maths questions.
Then HR
Then technical interview with a quant researcher.
Then a data challenge then i had to present the results of my data challenge.
Failed at this round

HR screen focussed on team work a lot. Technical was not too difficult, I may have just lucked out with the questions. Final round discussed ML techniques and their assumptions
2:30 hr OA contains coding probability game and quick math. Then a market making game round. Need to be quick. Then will be another market making game round. Both asking questions to make market.
