You can write I worked here x days in your resume, that's pretty much it.
Cons
Main ones are
- Management is horrible
- Expect you to get things done within a day or less
- Planing is nonexistent random ideas are pulled from thin air and expect you to complete it within a day
- No concept of privacy. New Year? Nope, Festivals? Nope, Weekends? Nope
- After a few small talks, they will talk like they own you
