PayPal

• Flexible working hours
• Free lunch, free breakfast, snacks, and soft drinks
• Work with people across the globe
• Provide entertainment rooms like table tennis, Xbox, and foosball

Need to stay late if you have a team meeting with people from different timezones.

Work on the weekend if you are in a different timezone, especially if you are in an Asian timezone while the PayPal release follows US time.

Bureaucracy.

Mostly start as a contractor, promised to get promoted in one year, but keep getting reasons to delay your conversion.

If you find contractors are expensive to begin with, you should not hire contractors in the first place. Even after deciding to hire only full-time employees, please consider the value that has been delivered by contractors during their tenure. Also, if you cannot fulfill your promise to convert in a specific time, don't promise it (maybe it did not come from PayPal directly, but please keep your "partners" under watch).
