I’m talking about after applying, how long does it take to hear back for an interview?

I started applying last week on Wednesday. So a lot of places had only had my application or resume for about a week. I heard it can take up to two weeks for someone to hear back. Is that true? I applied to over 15 places. I’ve already heard back from one place but it might not work out. Does anyone have any advice?!

I might not be able to pay my bills this month and I’m freaking out
