Best MBA programs for prospective IB applicants with no Finance background?

And by 'best' I mean most helpful (not necessarily highest ranking).

tl;dr Has anyone here made a successful move from something less quant-focused such as Advertising and into Investment Banking after getting their MBA? Wondering what MBA programs offer the best transition opportunities for students with no prior Finance experience interested in this field, and that also have strong recruiting.

I know that Yale SOM offers a "math bootcamp" for some admitted students with weaker quant backgrounds but that's not industry related and more so exists to strengthen math skills prior to the start of classes. It looks like MIT Sloan and Cornell Johnson offer Immersion programs that provide realistic simulations to the functions they'll choose to pursue at summer internships but its unclear how many of those students didn't already have some experience working in a Finance related field.

I'm wondering whether there are other programs offering something similar and what peoples' experience has been with their unique programs. Specifically, what efforts are made by the program to guide students looking to transition? I mean partnering students with unique mentors, advisors, or even additional coursework helpful for transitioning students.

Given that first year MBA Associates within IBD are typically less knowledgable than their Analysts and other Associates who have started out as Analysts, what schools put into place the strongest efforts to mitigate that and combat some of that knowledge gap for transitioning students?
