Question about weekly pay checks?

• online internet work
• black friday camcorder

I just started a job, and they pay weekly. Im not going to get paid this week (because i just started) but next Friday. So my question is will i get this weeks hours and the hours I work on the check I get next friday? Or just this weeks hours? Then the hours I work next week will be on the check after? If that makes sence? Im working through an agency called select staffing
