J'ai passé un entretien chez Optiver (New York, NY)
Entretien
First round is HR interview, all BQs. Second is Tech round, gave me a hard level Leetcode problem. Third round is a case study, I forget the detail but it is a really complicated problem, a lot of data details need to be noticed. My programming language is Python.
HR Phone Interview: All BQs
Online Assessment: HackerRank (prolly some python Qs just forgot)
On-Site Tech Interview: Probabilities and Statistics
Final BQ Interview
The whole process took about a month, casual interview vibe
