I’ll be doing the College Program in August, and the same still holds true - on my application I had to say that I would be available to work weekends, holidays, and overtime. I believe they have 5-day work weeks now, though. (I could be wrong, but that’s what I’ve been reading.)
However… I’ve read a lot of CPers who have taken on extra hours on their own, not because they were forced to. I’m planning on doing the same thing. And you do get paid extra for your overtime.
