I had a referral from a friend and interviewed with Mckinsey from Aug'19 though Dec'19 (Experienced hire) until the final round but was not offered in the end. The feedback I received was on Case Interview insights. By the way, it was encouraging to hear that 3 Partners had intense discussions as I was close to getting an offer. I was told by the recruiter to reapply in 12-18 months periods if interested.
I was browsing Mckinsey partner profiles on LinkedIn today (21 May'20) on the relevant industry, and one of the senior partners added me which I just accepted.
Could you please advise me on how I should proceed next? Its been only 5 months since the last decision was made and through my own research, I found out that this senior partner is the manager of one of my interviewers at the final round.
