How to long to hear back after an interview?

So I was lucky enough to have gotten an interview last Wednesday at my local In N Out. The interview went well but was fairly short. I did my best to smile a bunch, be personable and overall just outgoing. There were two other people interviewing me afterwards so I know there’s definitely other competition. The manager interviewing told me to keep an eye out for my email or a call to hear back about from them.

Tomorrow will be one week since my interview and I’m just curious how long it typical takes to hear back. I know every location will be different but I’m just curious if I should reach out to the store sometime later this week. Or if the lack of communication means that I probably didn’t get the job. Thanks for the help!
