I was given the impression immediately after an interview that all the employer had to do was check my references and if they all turn out OK then the job is mine. The thing is, it's been three weeks now and the employer has told me they're just waiting on a couple of references and should "probably" get back to me next week. This is concerning me because I'm passing up other offers. Does it often take so long? Could the employer be keeping me hanging on just in case something else doesn't work out? I never imagined it would take so long and I'm getting nervous!
