In store shopper questions

Hello,

I recently got an offer to work at Whole Foods yesterday as an in store shopper and I’m pretty excited. I wanted to ask how the job is and if I can work my own schedule, also is it normal for no interview and to do most of the background checks online? I still haven’t got contacted by a team leader or anything but I just filled out the background check and need to do the form I-9. I’m pretty excited as I start soon but still don’t know what to do but an email yesterday said “Your Team Leader will contact you to provide you with your schedule and details about your first day of work. “ but I haven’t heard back yet. Thank you.
