I sometimes start with a question like this, "Why are you leaving your current job?" You might hear a good answer, but more likely not. Too often, people are reluctant to say they want more responsibility or more money or a different product. More often, I'll start with a question about previous job changes, "Tell me why you went to the company you're working at now. What attracted you to that position?" Now I have some information about why the candidate went there. Now, I might be able to ask the why are you leaving question, but I'm more likely to ask about previous moves.
