Two Sigma interview questions

This review focuses mainly on the phone and technical interview. The phone interview went well. The JR person explained the company and what it does very clearly and concisely. The atmosphere was relaxed, but I remained guarded as to not say too much. The next portion of the interviewing process was the technical. The technical interview starts with a coding challenge. The coding challenge is done using Interview Street website. There are two coding problems to solve and two hours to do it in. There are some samples out there to get a feeling for the tests. I thought that the tests were a little heavy in use of container classes like STL to solve the problem.
