Useless

Applied for a job that was advertised by Office Angels Manchester. They required me to come in and sign up with them before they would arrange an interview and mentioned that with my CV they would have several vacancies that could be interesting.
Once the interview was arranged, they called me numerous times with useless advice like, I should put my best foot forward, be perky etc. (because with 20+ years of job experience, I clearly need advice how to go through a job interview). Once the interview was over - silence! I tried to chase them up to give me feedback, if they had heard back from the company I interviewed for. Nothing. I was promised the agent would call back, this never happened. Seems I didn't get the job.
I would say, this might have been an exception. But three years ago I had contact with the same branch of Office Angels and exactly the same thing happened. Super annoying before the interview, then, when the customer didn't bite, they dropped me like a hot potato and didn't even bother to inform me.
Seems that is their way of doing business.
