The questions you should ask in your job interviews might surprise you.
You always want to ask questions during your job interview because (1) it shows that you researched the company, (2) it helps you have a more relaxed and productive conversation, and (3) it helps you uncover information you can't get anywhere else. It's that third one that's the tricky one. Some of the information you need is not just 'inside' information about the company and the job.
You can have a much better, more successful interview (and a better shot at the job) if you ask two key questions. They are what I call strategic questions that give you big clues as to what the hiring manager is hoping you'll say so he can hire you. You can nudge him into making you the offer just by asking these questions and using the information you get from them.
