Why did you leave your previous employer? Or…why are you leaving your present job?
This question doesn’t require a long-winded answer, and it is best to be positive, not defensive, especially if you left because of problems with your boss or peers. Career experts all agree: don’t air your frustrations about previous or current job, or the people involved, Interviewers may interpret this to mean that you’re a chronic melancholic, or that others find it difficult working with you.
Don’t fudge on information about why you left the last job; this can easily be checked. And if you are dishonest, all of your answers might be regarded with justifiable suspicion.
Perhaps the best answer is simply to state that you are seeking greater opportunities, technical challenges, or responsibilities. Don’t use “more money” as a reason. More often than not it is obvious that a candidate wants a better salary when changing jobs.
