Agree w/ Nirmit on the 'momentum' concept, but let me offer up a different general take:
- Many/most candidates vastly overestimate their preparation level
- Admission rates are low, with some figures as low as 1% and less
=> objvectively, mathematically, your and everyone's odds of being properly prepared & receiving an offer are low.
I would recommend you apply to Tier2 first, then perhaps the one of MBB that you expect to like least. Assuming you do get interviews (far from a given), you will quickly get very clear indications of how well you perform. If you do well, hurry and apply to the last couple of companies; if not, cut your losses and go back to the drawing board: do you need a stronger profile? more prep? better prep? just luck? (that last one, probably not!).
If you do apply and get rejected, you will likely not be able to reapply for another couple of years. Don't burn yourself applying everywhere if you don't know you can go the distance.
Hope that helps. Good luck -
