Did I even get hired?

I had my 1st ever job interview today at 4pm. During the interview, I panicked inside but managed to keep my composure. At the end of the interview, they said they'll call me back and next week would sound like a reasonable time for me to call them back if I have't heqrd back by then. they said they'll call me later because they had a hefty list of applicants and they'll have to discuss if I get hired with the other hiring manager. At the time, I thought it sounded good and I thought the interview went well, but now I am not so sure and I am worried that I fumbled it. Don't y'all typically get hired on the spot?

Edit: I forgot to add that they also told me I should bring my school id next time we remeet. Definitely fumbled it. Sad.
