The interview at UPS was fairly easy. I met with the project lead and 2 other leads. The technical questions were pretty simple and generic C++ questions such as inheritance, polymorphism, constructors, etc. There were also a few SDLC concept questions. There were no white board exercises. A large part of the interview was also non-technical. There were many questions in which the interviewer attempted to reveal my character and personality. Overall it was a positive experience but not a particular difficult interview in all.
