I applied online. The process took 1 week. I interviewed at Optiver (Amsterdam) in Nov 2023
Interview
First stage was all technical I did not make it past this stage. It was 2 programming questions and a series of cognitive ability questions. It took about 4 hours overall.
Interview questions [1]
Question 1
2 rather difficult programming questions since the amount of time given was 2 hours for both.
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.

Question 1
How many bits do you need to store a number up to X. And how can you represent that.
