Again most of the top MBBs hire from top b schools with good background & stellar acads (experience from good companies- Amazon, bain, Mck etc) or CA rankers. So in case you want to go for these companies this is the ideal path (again you would have a shot at it, nothing is guaranteed). The work in these companies are good but low wlb (compensated by high pays). Then comes the 2nd tier - Acc strat, Deloitte etc. here the work is shit but pay is okay.
All these things were addressed with PM roles - good money, good wlb however such companies are rare and difficult to get into - MS, Atlassian etc. but even for these companies the pay is not stellar as for Tech roles or MBB roles
