On many cases, you will receive equipment that is damaged/broken. You do not have a set schedule for work. The offer email given to me had a set schedule and when I mentioned it to the supervisor they said it was a mistake, but based on other reviews it is an ongoing problem to give false information in offer emails/letters. You have to compete for schedules and they do not accommodate you if you have another job/have other priorities unless you score high on a test.
