Questions every Candidate should ask a potential new employer

Over the years I have conducted my fair share of interviews with potential new employees for the different companies I have worked for. In fact my company is currently looking for a few good developers now. What has always confused me is the lack of questions asked by the potential candidate. Sure they ask the standard stuff like vacation, benefits (pay, 401k, insurance), work/life balance, company history. However, most fail to even mention anything about the team, the environment or the companies philosophy towards software development. If you ask me, knowing how the team is structured/ran is more important in some respects then ‘standard questions’.
