McK R2 timeline

I had my final McK interview on Friday (6/5) and was flown to NYO. My preference was Chicago office but for some reason I had to fly to NY for the interviewing event (multiple people interviewing for the same practice? Not quite sure) My last interview ended at 4pm ET and the last interviewer (virtual from Chicago) said they will try to get back as soon as possible but by Monday for sure. I did not hear anything back Friday night and flew back home. Should I still have hopes for an offer call on Monday? interviewers seemed impressed and happy overall, i don’t think I messed up anything and they agreed with me and gave positive feedback during the interview
