Randstad US Account Executive/Recruiter interview questions

They aren't afraid to drag you along and waste time. They thought they wanted me but didn't know where to put me. I interviewed for this team, that team, multiple positions, IQ tests, personality tests, aced them and was told that the offer was basically a done deal and it would be out to me soon. After a week of not hearing anything I ask about it only to find they gave it to a referral they got that they met with once. I had been brought in for 5 interview stages at this point. It was a very frustrating experience and left me with a negative view of the company. If they don't value your time in the interview process what are the odds they will once you have the job?
