United Wholesale Mortgage (UWM) .NET Developer interview questions

I was contacted by a "Sr. Talent Acquisition Specialist" he initially asked some pre-screening questions. Difference between Interface and Abstract class, do you participate in any programming events, what was the most difficult thing to learn about programming. They then had me in for a in-person interview with two people. They had amazing kitchens, cafeterias, and workout centers. Oh, and valet parking. They actually frowned when I said "valet parking wasn't me" But why became pretty clear. Their benefits were some of the worst I have seen. Little vacation, a few holidays, and $2,500 max toward retirement (do not expect to retire in your lifetime on that little of saving). To me it looked like they spent all the money on getting you to stay there long hours. They certainly picked up on my feelings because I was not offered anything. After the interview they took me on a tour. The spaces were wide open and colorful cubicle farms. It was a little strange as everyone was always smiling and greeting. It almost seemed staged or they really did only hire people who love this type of atmosphere. I feel this would be a great place for a college student or beginning programmer but probably not the best place for Senior level developers.
