How long does it usually take for internship to deny or respond to you?

Recently I applied for internships at a big company, and after a while of no responding, I gave up hope. But last week they emailed me back saying "The hiring leaders are still in the process of making decisions regarding next steps." It's been a week, and there are no follow up to that email, nor any other emails from different Internships company that I applied for. At which point should I just give up and accept that I'm ghosted? Thank you!
