I applied online. I interviewed at Optiver in Jul 2025
Interview
Phone interview over Zoom with technical hirer. This was a 30 minute interview consisting of general behavioural and resume check and work background. Expect your most relevant experience/project to be asked.
I took the OA, and it was very hard. It was 90 minutes and nothing was that hard conceptually if I had more time, but they just ask you to understand A LOT in 90 minutes and write a lot of code.
Interview questions [1]
Question 1
Something about battery system and how to design it
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.
