you can get asked questions that you completely blank on....you can get stuck on ethical questions...and no, the blanking isn't completely the interviewers fault, obviously we can be prepared for all the questions, but some ppl make it stressful, and not like a conversation at all, more like an inquisition, and then you blank when you know the answer...or not even just blanking, but just stumbling over your own words due to nervousness, etc.
i.e., i had an interview where i was asked questions where the answers were told to me before the question, and then i had to answer the question (not drexel).....that's a bad interview
i hope that helps, and if you haven't had a stress interview, or just don't succumb to nervousness, then congrats, i wish i could feel that way as well
