The interview process began with an initial behavioral phone screen with a human resources representative. Following that, there were two virtual on-site interviews with engineers. One session was a technical deep-dive focused on coding, and the other was a comprehensive system design interview
Interview questions [1]
Question 1
why optiver?
what's the most challenging project you have
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.
