in general you cannot be considered for more than one office at the same time, although in some application you can select multiple offices (in which case you will be in the process for one office only anyway). As a consequence, if you apply for the Milan office you will either:
- Be invited for interviews; after that you will receive an offer for that office or get rejected
- Get rejected without invitation
After a rejection there is normally a waiting period (in MBB the standard is 24 months) before you can apply to the same or other offices (some people try to hack the system using different emails but that doesn’t always work).
I would recommend anyway to apply via a referral, whatever office you choose – this allows to increase the likelihood to be invited and at the same time understand the real recruiting needs; you can find more on referrals at the following link:
