The right answer is always whatever makes the interviewer think you're smart. I bullshit my way through these because I have zero respect for them. Every interview question asked to me should be directly related to the job description. Thankfully I'm a professional bullshitter and they're easy as cake because impressing people who ask those questions is usually easy by the nature of the reason the question is asked in the first place (to appear competent). Love getting those jobs though!
