I prepared really well for case interviews. Unfortunately, I stressed out and completely bombed the very first question on the first case and freaked out, messing up the entire first case.
I did reasonably well on the second case.
I regret what happened on the first case - it was my fault. How soon can I even think of reapplying and when I do reapply, will BCG even consider me given how poorly I performed on the first case in the first round?
