The process took 2 weeks. I interviewed at Optiver (Amsterdam) in Oct 2023
Interview
The interview process at Optiver typically involves multiple rounds, starting with an online assessment, followed by phone interviews, and concluding with on-site or virtual technical interviews and a behavioral assessment to evaluate fit and skills.
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
Got an online coding test invitation immediately after submitting an application. It took three hours, but I didn't proceed to the next round. I don't remember all of the questions, but one was coding up a trader analyzer
