Your resume gets you in the door, but your performance in the job interview ultimately gets you the position. That is, if you don't botch it.
The questions you face at every job interview is different because the companies and people asking the questions vary so widely. However, there are a few questions that seem to have universal appeal to hiring managers doing the asking, and those are the questions for which you can and should prepare. They are questions meant to either throw you off your game, make you think on your feet, and/or determine how you handle yourself under pressure. Sometimes it's not even your answer that matters, it's how you compose yourself while answering.
So while you can't be prepared for every curveball, you should definitely think about how you're going to answer these nine questions that pop up in most job interviews. Good luck.
