Interview vs. Interrogation?

Nice intelligent question that. Had to think about that for a short while. Ok here goes. My feeling is that an interview is something that you go to voluntarily, because you want something. An interrogation I think is something over which you have no control, and the other person wants something from you. Therefore, you can prepare for the interview by making your own list of questions, either written down or in your head. Whereas in an interrogation you will probably not be given the opportunity to ask any questions. Ultimately it is a question of the power relationship between the person being interviewed/interrogated and the person doing the questioning.

First, an interview is voluntarily answering questions. Interviews are related to securing employment or sharing information about yourself with a writer or media reporter for publication or broadcast. An interrogation is the compelled answering of questions in a legal situation.

I would believe an interview is a voluntary thing, whilst your generally still quite scared (I hate them) its meant to go on to a better purpose, whether it be a new job, to clarify your name etc. An interrogation would be something that is done without your consent and has a lot more of a harsher tone to it. Whilst you may be able to 'leave' it really isn't an option. Hope this helps :)
