WTW Software Developer interview questions

I had two phone interviews and then went in to the Minneapolis (Bloomington) office for a half day interview. The processes consisted for four interviews with a project manager, two developers, and the team lead. Everyone was courteous and friendly. It was a junior level position, but I was a little disappointed by the lack of technical questions. I was also disappointed that I did not get any sort of response after the process even though I sent a thank you letter and inquired by email if a decision had been made. I spent more than four hours interviewing in person, so one would think that it would be common courtesy to give a simple yes or no. I have to believe that they were waiting for the "perfect" candidate as the job was still posted more than six months later.

Approached for a .NET developer position by a recruiter who scheduled a phone interview. It was a 30 min interview with questions about my professional background and my salary expectations. I got a call from the recruiter 1 hour later in order to proceed to the next phase of the process in which I was asked to develop an application that implements a mathematical algorithm to execute some financial mathematical calculations.
