At my school it was the summer term of 4th year.
I didn't like it much at all, I think the teachers were a little stunned by my negativity in the exit interviews as they were expecting people to come back saying "actually it went better than I was expecting! So much more fun than school work!!". I said it was a waste of time and my time would have been better spent studying. I didn't actually get a job until 6.5 years later anyway. Was also a tad jealous about the fact that some people got gifts, money etc from their employer.
