Every interviewer has a version of these: Tell me about yourself. Why do you want to leave your current job? What is your greatest weakness? Where do you see yourself in five years? Why should we hire you?
Prepare a ninety-second answer for each and practice saying it out loud. For the weakness question, name a real one and say what you are doing about it. For salary questions, give a range based on what you learned in the Labor Market Info center and let the employer name the first number if you can.
