I applied through university. The process took 2 weeks. I interviewed at Two Sigma in Aug 2015
Interview
I got a email from a recruiter a while after I had submitted a resume. We set up a time for a brief introductory chat over videochat, which the recruiter did not show up for. I asked some follow-up questions about the company over email but never received a response. At my suggestion we simply moved onto the next step of the interview, an online coding test. The coding test took three hours and was moderately difficult. After a week of no communication I inquired and was told that they did not want to continue because I ran out of time to implement the last step to one of the problems.
first interview was 60 minutes long with a leetcode hard question. second interview was 2 back to back 60 minute leetcode hard with emphasis on data structures. each interview had a 5 minute introduction and 10 minute at the end to ask questions
Standard medium difficulty hackerrank. The question involved decoded an encoded string. It was not something I had seen on LeetCode before and I think was unique to the company. The question was not that difficult but I ran out of time right before I could finish answering.
