I applied through an employee referral. I interviewed at Optiver (Kānpur, Uttar Pradesh) in Jul 2021
Interview
There was numerical test consisting of 80 questions to be solved in 8 minutes. Marking scheme was aggressive, -1 if you leave a question, and -1 if you get it wrong. 55 was considered to be a good score. Then you had HR interview and then technical rounds where you were grilled on market making, probability and statistics.
First you send your CV and then you get different "challenges". One for sequences, one for probability and one for coding. All of them are quite hard, especially the probability one.
