The questions are very predictable. Write some python scripts for the OA, it is as described online. If you really care about getting in, find someone that does the interviews a week ahead of you and you will crush them. If you can't find someone buy recorded interviews, some sell them. While I didn't get an offer last year, I followed the steps above to get it this year. Optiver is completely unable to assess candidates based on their skill level. They only check if you answer their set of questions.
Don't get me wrong the interview is hard if you don't know what is coming but I know from 4+ people that each got the same question. I did not take the offer as I've never felt so uninspired by a company. Go to JS or Citadel or any other company.
A bit anxiety inducing, there were two developers observing and asking questions. Real-time problem solving required, conducted on Hacker Rank virtually, video and mic enabled - quite nervewracking to say the least
I had one round, which was an online HackerRank test. I wasn’t able to pass all the test cases, and as a result, I did not progress to the next stage of the process.
A lot of interviews. Started off with a call, then some online tests. Then a technical interview. Then a live coding interview along with a architecture interview. Last step would have been final day interview but I did not get that far.
