Me postulé en línea. El proceso tomó 5 semanas. Acudí a una entrevista en Optiver (Ámsterdam) en mar 2021
Entrevista
1) Hackerrank test 48 hours
2) HR interview
3) Technical interview
4) 6 hour interview day, 2 interviews + presentation
Overall they expect you to put *a lot* of time into applying. HR doesn't do a great job preparing you for the interviews. My advice would be to practice well ahead, and unlike what HR says, make sure not to ask questions during the technical interview. Make sure to ask good questions otherwise, they like that.
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.
