DON’T say a number. Why? you have the least amount of leverage possible at this point, assuming you’re early in the interview process. You haven’t finished interviewing with them, they don’t know if you’re any good or if they even want to hire you. So you can’t command a high salary right now. If you go too low with your price, they’ll hold you to it later. Go too high? You’ll scare them off before they even know what you’re worth!
Even so, if you're asked, provide a sharp, on-point answer. Be clear and precise. If you're a great problem solver, don't just say that: Provide a few examples, pertinent to the opening, that prove you're a great problem solver. If you're an emotionally intelligent leader, don't just say that: Provide a few examples that prove you know how to answer the unasked question. “I’ve heard great things about the work environment here from a few colleagues. And when I saw this job posting, it seemed to match my skills very closely. For example, I saw on the job description that you need somebody who’s an expert in Java programming. This is what I focused on in both of my previous positions, and was even the focus of my academic work before graduating university. I consider myself an expert in Java and it’s a skill I hope to continue specializing in.” Here are the 50 most frequently-asked questions that are posed in interviews. Be prepared to go into some detail about your work history; you may also be asked behavioral or situational questions which require you to provide an anecdote about how you have handled a work challenge in the past or, alternatively, how you would approach a situation in the future.
