Bain waitlist vs. McKinsey exploding offer (NA)
I am in a very privileged position to have received a McKinsey offer for the associate position in NA. Previously, I had attended the Bain summer program for advanced degrees but unfortunately bombed the final case interview and did not receive an FT offer. The recruiting manager communicated that I was placed on a pseudo-waitlist and that they will reach out to me at the end of August or early September. Now I am in a bind. I know it is easy to just accept the McKinsey offer and never look back, but Bain has always been my top choice and I really felt at home with all the Bainies during my mini internship. My interactions with McKinsey have so far been more business-focused/professional, which is fine but I just didn't feel the sort of connections that I had at Bain. Therefore, I have two questions for the more experienced folks here -
1. Would it be possible/smart to leverage the McKinsey offer to try to push Bain HR or would this seem unprofessional?
2. Since the McKinsey offer "expires" in two weeks, would it be an option to ask for an extension? How bad would it be to accept the offer but eventually renege?
Thanks in advance for any tips or suggestions!
