Interview

I just had my second interview on Saturday. It was scheduled for 11 PM, but I arrived 30 minutes early, so I actually finished my interview at 10:58 PM.
The DM told me that the SM would let me know how my interview went and what the next steps would be. He also mentioned that she had Saturday and Sunday off, so I should hear back from her on Monday.
I texted the SM late on Monday, but she hasn't replied yet. Does that mean I failed the interview? Should I call them tomorrow or keep waiting?
