It was technical phone interview with code being shared via an online service. After logging into the service I was given 4 questions including a Hello World and a syntax review. No question was terribly hard and all could have been answered by an entry level developer with access to Google and a compiler. All of the provided questions were related to C# and .Net. No algorithm or theory related questions were given and the interview was done in 15 minutes, when it was originally scheduled to last an hour.
When I found out that they had decided not to extend an offer, the reason given was that I appeared to be more of a Java programmer than C#. Oh well, at least the story got me entrance to this site.
