3 prob & stats questions - first round tech interviews. Interviewer is a trader. Questions are classic but need to be answered quickly so need some practice before the interview. I heard there will be 6-7 rounds overall

A very standard prcess. Firstly introduce myself based on the resume. Some questions based on my previous experience are also expected. The final step is a short brain teaser which is more like a routine with very low weight in the interview.

3 rounds zoom interview, first round with qr discussing about resume and some basic stats/linreg, second round with a pm with multiple math questions, and third round with the hm, talking about option pricing.
