I haven't had any experience there either.
It's pretty cool, even though yesterday was hell on earth. First day - I got half an hour of going through my duties (basic clerical stuff) before I was on my own for four hours, surrounded by busy medical people and disgruntled ill people. It went mental busy, the computer system died for an hour, I got shouted at by an angry pregnant woman and everyone was multi-tasking like mofos. It gave me a headache. I was relieved to get out though on reflection it was probably more satisfying than my last job
Today was very nice, a lot more relaxed.
