I applied online. The process took 2 weeks. I interviewed at Optiver (Amsterdam) in Oct 2016
Interview
Applied through Stack overflow Careers. Got a reply within 3 days to do a Hacker Rank test in 10 days. I was pathetic with the HR test so got rejection email after 2 days. My HR test score was 12, haha, loser me.
Interview questions [1]
Question 1
A Hacker Rank test that had to be attempted in C/C++/Java/C#. It has 4 questions: 2 were about OOP/Classes, 1 was about array of dates and another one about trees.
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.

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