Interview tmr (CAN)

So ive been applying to everywherre like crazy and last night i applied to Mcds and got the generic “interviewers calender is full” but this morning I was scheduled for an interview for tmr.

I’m looking for a second job rn because its summer so im oretty free, and my current job has very limited shifts (4-8pm, maybe max 4 days a week). I did upload my resume so the other job is there and I filled in the availability as I have it and I was still chosen. When im asked about availibility in the interview, should I mention the other job specifically or just say those are the times with no certain reason? Does it look bad to have another job?

Also I was scheduled with the Ai but ive also appkied to other places with this same format and this is the first time i actually received an interview time. It also said go in and ask for “name” at the front desk, so im assuming the manager is aware, but ive seen some people say that this platform doesnt even notify the manager and you end up going in with nobody available to interview you, im thinking i can call in advance? Any advice at all would be helpful! (Also if anyone says this is a horrible job im just looking for a second income so i can just thug it out for now, ive tried everywhere)
