I was asked to come to Los Angeles for an interview (as one of 3 finalists), with an offer to pay for my parking and meal expense. I drove 400 miles, arriving the night before. When I got to the client no one was expecting me, the recruiter hadn't bothered to book an actual interview, the hiring manager was out, and the recruiter had no desire to cover my expenses. I noticed the guy the client finally hired left recently...before a year was up.
