First there was a long OA of about 3hours. Then, there was a zoom interview on the card betting game with the recruiter. I didn't make it to the next round.
I applied online. I interviewed at Optiver in Jan 2026
Interview
Got OA after application. Four parts: coding, probability and statistics, beat the odds and zapN game. Three coding are all dp. Each prob question needs to be answered in 90s. You have 30 min to finish 25 beat the odds. ZapN consists of 3 mini games testing your reaction, concentration.
Very smooth, the HR just asked me why Optiver, why quant, what is your strength and weakness, what is the career plan in the next 5 years, but I did not answer very perfect
first round of math probability
2nd of betting. the platform was bit hard to use. Recommend to get some training if you can find the resources. both interviewers were nice
