If you at all care about the job you're gonna do expect to be run into the ground, take on all the responsibilities of a supervisor without any benefits, do the same if not more work than long time employees because they have given up because the company drains them, and expect to feel worthless and be basically neglected (especially if you're due a raise). The few upsides are flexibility and they'll feed you during holidays. The Downsides are you can be locked into your shift hours after your supposed to be off, neglect, weak management, and toxic coworkers.
Trust me. It's not worth it.
However there are a few people there who really, really try their hardest. But the storm around the company is just too strong.
