The process took 2 weeks. I interviewed at Two Sigma (New York, NY) in Nov 2011
Interview
The process first starts with a two hour code test. They should both be pretty doable if you use Java and think through the problem.
The next stage is an on-site interview. I'm not too sure who everyone else has been interviewing with but my experience was pretty positive. I met with two engineers who asked me some simple interview questions and about my past experience. I didn't do too well and could tell when I was told I was done for the day. Overall though, everyone was pretty courteous.
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.
Interview questions [1]
Question 1
Decode a string encoded using a specific encoding algorithm.
It started of with one phone screen, then if you pass you have 2 back to back technicals, then 3 1 hour behaviorals, hiring committee, and management committee. Standard Leetcode and behavioral questions.
