This question falls into the general category. Interviewers can ask any type of question at any time during the interview. Rather than trying to predict how the interview will flow and the type of questions you will be asked, you should be prepared to answer any question.

The more you know about these three topics, the better prepared you will be to answer any questions you may be asked.
