Are interview questions repeated? If yes, how often?

The best way to handle this is give a good answer to the question just like you did the first time. Getting frustrated about having to repeat yourself will only make you look bad.

In my experience this will happen more often than not. Obviously not in the same sitting, but throughout the interview process in one company, yes there will be repeated questions.
