J'ai postulé en ligne. Le processus a pris 2 jours. J'ai passé un entretien chez Optiver (Londres, Angleterre) en sept. 2020
Entretien
I received a test with three days to solve it. The test consisted of two problems which I solved. I was contacted a few days after by the recruiter who thanked me for my time but they wouldn't be going forward with me. When I asked for extra feedback I was told that my implementations didn't pass the hidden tests. When I asked for extra feedback, they said that it was company policy not to share specific feedback! The odd thing is that I tested one of my implementations on leetcode (on the same problem) and passed all 100 tests. Overall it was a very bad experience and I wouldn't recommend losing any time on them.
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.
Questions d'entretien [1]
Question 1
How many bits do you need to store a number up to X. And how can you represent that.
