I got hired!

I called an autozone and asked for a manager and we talked for a little and he said he has couple other people he wants to call and he’ll make a decision by the end of the day. He ended up calling me and offering the job. I got an agreement contract today in my email. I signed it and went through all the pages. The email also said I would get instructions for the next steps in the process after I submit my response. But after I submitted my response I didn’t receive an email. Do I have to wait a while before I receive another email? Or should I call the autozone again?
