Ring phone, ring!!

Waiting...I hate it. I had a job interview this afternoon, and now I'm sat here hoping that the phone will ring. They've told me if I've got the job I'll hear by 5:00 PM, so with less than an hour to go before the deadline, I'm not feeling optimistic. I don't think my lesson went particularly well, and even though I left the school feeling quite happy with how the interview part went, I don't honestly think I've done enough to get the job overall. I'm already dreading the feedback I've asked them to send me (assuming I will be unsuccessful), and I'm wondering just what I must being doing wrong in these situations. The joys of job hunting, eh?!
