They gave me a HackerRank for the first round. It was 3 days long and reasonably hard. Took me about 10 hours in total to finish and I tested a bunch of edge cases and passed 100% of all their cases as well. I was pretty proud of myself for my performance but a week later, I was rejected. Honestly, there's a slight chance they did not like my coding style but I think more likely they just stopped hiring and had me spend 10 hours on a coding challenge that did not matter because even getting it all right and testing for all kinds of edge cases did not lead to at least a phone screening. I feel like they wasted an entire day of my time and it feels insulting.
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.
Ho sostenuto un colloquio presso Optiver (Amsterdam)
Colloquio
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.

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