Handed in my cv in person

Im 17 years old and I gave up applyong for jobs online so i decided to give my cv in person. I saw a job posting for a restaurant as a team member on Indeed so I decided to go in person. I reach there and give the cv to the manager. They seemed interested in asked me part time or full time I replied part time. They seemed happy and I believe they will contact me later but im not sure. Is it likely that they will get back to me and how long after usually? Its been 7 hours now.
