Cisco Software Engineer I interview questions

WORST interview experience ever. It started with a referral for application level position. Got an email requesting time for phone interview. After, deciding that got call from the same engineer that they have to fill the requistion so you will have to come onsite this week. So I rescheduled other interviews and went for the interview. When I reached the building my point of contact was not reachable. I waited in the lobby for 15 minutes and a gentleman from completely different team came and said I will interview you for my team. So from application team to a low level embedded team, what a jump. One of the interview asked me what is the balanced tree. I started explaining about the height and how difference in the height gets to the balanced tree. I was shocked to learn that interviewer's definition of balanced tree was a binary search tree. After explaining the interviewer and interviewer searching on the web for 5 minutes said there are these two definitions of the balanced tree and let's move on. One interviewer was very rigid about the hash chaining implementation. They wanted specific answers to specific questions rather than the thought process. The whole process was wierd.
