I applied online. The process took 1 day. I interviewed at Optiver (Amsterdam) in Sep 2015
Interview
The interview involved a 1-hour written test and then an HR interview then lunch and regular technical interviews, it was overall friendly and professional, I enjoyed it.
I was surprised by how professional the recruiter was, it was on par with top IT companies such as Google and Facebook.
I didn't accept the offer for personal reasons.
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.
