This is obviously an unusual case and I am just sharing my opinion here, so no general rules, and other coaches may have a different view on this.
1. This seems very challenging, if not unrealistic in "general practice"
2.HIghest probability to succeed would be to leverage your expertise and apply directly in a posiiton/industry where you can add value (e.g. M&A)
3.Select cautiously the firm you're applying for. MBB might no be the easiest and most relevant for you to apply for. HOwever boutiques might be more relevant for you
Hope this helps
