Will I get good hours at Starbucks?

So I am hopefully going to get a job at Starbucks. I have my background check going through and they gave me the new hire packet about the job. I'm leaving my current job because I only get like 2 hours a week so I feel like i'm basically unemployed. I left an open schedule at Starbucks and checked that I wanted to work part time which is (12 to 35 hours a week)

I wouldn't mind working 35 hour weeks, i'd love the money. But I would rather not only work 12 hour weeks. I'd take the job even if I only got 12 hour weeks because it's better than my current schedule at my job I have now. but do you think they'd give me at least 20-30 hours?

It's a pretty starbucks I will be working at if they hire me.
