Interviewed recently with Perot and know some people who work there. All want to leave (I was just curious which is why I went to the interview). The interviewers were ill prepared - interviewer 1 kept looking at the other one waiting for her to ask a question but she was too thick to know what was going on. If that's how they do business, then forget it. Also, their salary and benefits are pretty poor so avoid it like the plague if you have a better offer. They're also heavily into NHS work here in the UK so don't expect much variety.
