Don't set up interviews with employers where you really want the job until you have had several "practice" interviews.
This is an email I just received from a person who took the course:
I just got back a few hours ago from my first of a 3 part interview with xxxxxx. It went extremely well, Assuming I'll pass the background check, and how can I not, I've already been invited for the 2nd interview. This interview went so well that it took 2 hours instead of what was supposed to be 30 minutes and turned more into a job training session than an interview. It was fun and I learned a lot.-RW
Your advice on getting practice interviews really paid off. I've never had to interview for a company before, I always knew my employers prior. Last week I went on two interviews I knew I didn't want, and though they were not the same type of caliber interview, it really helped me work out the kinks. If I had gone in there cold no telling what would have happened. But the practice interviews, even though one of them really was a throw away company (let me tell you) really helped me prepare.
