Applied at Aerie for Unknown

I recently had an interview with Aerie for a position that I felt went really well. The manager and I had a great conversation about my experience, and she seemed genuinely interested in what I had to say. She mentioned that I should expect to hear back from them either the same day or by the end of the week, specifically Friday or Saturday. If I didn’t hear anything by then, she suggested that I should give them a call. I’m feeling a bit uncertain about whether this means I might receive an offer or if I should indeed follow up with a call. I'm considering reaching out on Monday for an update.
