One time I went for a teaching job at Dorchester Jail. They said,

Well you've seen the place, tell us what you think of it......

And I said, Well I think its the most awful place, i've ever been in my life. Like something out Charles Dickens....you know the press yard, Newgate, The Marshalsea, and all that......er, isn't that the idea?

Apparently it wasn't. I didn't get the job.

Interviews I have mishandled and completely blown.... there should be a thread on that! In fact I could probably write the first 100 or so messages myself.
