I applied through university. The process took 3 weeks. I interviewed at Optiver (Chicago, IL) in Oct 2011
Interview
first took an online programming test. The test was more like an IQ test rather than programming. Then a phone interview with a developer, very basic stuff. The superday began with a programming test and then 4 back to back interviews. Expect questions you can see in a datastructure/algorithm class midterm for the test. The design interview was interesting. The overall organization of the superday was really good.
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.
Interview questions [1]
Question 1
How many bits do you need to store a number up to X. And how can you represent that.
