Plusnet Technical Support Advisor interview questions

Online application, followed by a telephone interview about a week later. I successfully passed the telephone interview and was invited to an assessment day at Plusnet's offices in Sheffield. Assessment day consisted of a group exercise, 2 simulated calls ( one normal and one angry customer), a face-to-face interview and a technical knowledge test. The technical knowledge test consisted of some seriously nitty questions that you wouldn't know the answers to unless you had prior experience of IT helpdesk/tech support, which I thought was unfair as the job description specifically said no previous experience required. At the end of the interview, we were told that we would be contacted within a week to let us know whether we were successful, but Plusnet never contacted me. They conveniently don't provide a direct number for their recruitment team so you cannot ring them yourself, you can only speak to Customer Support who fob you off with false promises. Pretty disgusting, really. I think it's safe to assume that I didn't get the job.
