There are many things that you have to consider before you accept that job offer. First of all,
Ask why the former employee left: Try and do an investigation into why the former employee left the organization. It might just help you dodge a bullet.
Ask about off days: You have to be clear which days you would be working. So that they would not call you Sunday midnights to come and work.
Ask when and how they would pay you : You don't want your salaries to be delayed. And you won't want them to pay you through a means you are not comfortable getting salaries.
