What questions should I ask before signing over to become an IT contractor?

Hello everyone.

I am recent graduate an I’m relatively new to the staffing firms providing short to long term contracts. I am on a final interview with a client from a contracting staffing firm.

I was brainstorming of what appropriate questions should I ask the contractor before signing over the papers, but I am coming up a bit short. I’ve been searching through various tech sites and I am unable to find a basic list to utilize.

Would any of you have any recommendations/suggestions?

Thank you.
