GS IBD behavioral

So, I did a superday for GS IBD SA position this recruiting season and did not get an offer.

I had three 30mins back to back for the superday and thought I did well, better than other superdays.

I know for a fact that my technical knowledge was spot on and they had run out of questions to ask me. I know that fit is more important and also that its not about being good and nailing everything spot on but being better than your competition.

Based on this, the only reason that I can think that I would get dinged would be due to my behavioral answers. I know that GS has their spin on behaviorals. Out of the ones asked, the following stood out/I remember.

If you were working with a team member and for some reason the team member had something come up/unable to do their job, and there is a deadline, how would you handle the situation?

If you were working by yourself and there is a deadline, and you know that you will not be able to finish the work, what do you do?

If you made a mistake and it was a minor one, but you caught it on the powerpoint during a meeting, how do you handle the situation?

how would you answer something like this/what is the proper way?

Also, what are some other possible reasons on why one would not get the offer after a superday, given that their technical and behavioral are good? And, also the interviewer likes you as a person/wants to work with you.
