Pros

Pays well, but they will work you into the floor for it

Cons

Inconsistent management, no upward mobility, experience depended highly on manager; get a bad one and you’re screwed. Cultlike atmosphere includes firing people for spilling coffee and demanding everyone on site park the same way.
