Don’t want to get my hopes up

sally

I had an interview yesterday morning online and at the end of it she told me she would get with HR and let me know by the end of the week she said”which is tomorrow because tomorrow is Friday” well I’ve been waiting and checking my emails all day and I didn’t receive anything. Should I just assume I didn’t get it and move on or do I still have a chance to get something back on Monday. This would be my first “real” job so I don’t know anything about interviews really I need HELP🥲
