The most unexpected thing was that I wasn't asked any of the standard questions that you would expect where you are asked to describe certain terms. For example, "What is a virtual constructor?" or "How would you find and fix a memory leak?". I was glad to not be asked such questions and that they focused on the most important thing: can you design good software to solve a problem. It was also nice that I didn't have to do any whiteboard coding. The whiteboard was only used to describe the problems by the interviewers and my proposed high-level solutions.
