Initial meeting was via Zoom plus connection through an Optiver-built website. Brief introduction from the interviewer and immediately jumped to questions. Mostly focused on make as much money as you can type of exercise on a number of available bets.
Interview questions [1]
Question 1
Series of available bets on cards/dice/etc. Make as much money as you can.
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.
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
