Applied at Dunkin' for Unknown

I applied for a position at Dunkin' and made it to the interview stage. I submitted my availability for the interview, but it's been 5 days without a response. I'm starting to wonder if I'm being ignored. I know there could be various reasons for the delay, like the hiring manager being on vacation or perhaps they found someone else. I think I might need to follow up with a call to get clarity on my application status.
