Hi,

I would not submit a second application as the global recruiting system will very likely identify and reject your profile.

Instead, I would get in touch with the BCG Team during the campus event AND/OR the Office A Team (depending on your case) to explain your situation/motivation to change.

I can imagine three potential reasons to re-apply to a different location (there might be more):

1. You want to increase your chances to get an offer by interviewing at 2 offices – this one is not going to work; their recruiting system is global and once you are in (and do not get an offer) you cannot re-apply during the cooldown period (18/24 months)
2. During your first application, you specified location B as your first preference but got only invited to location A for an interview in November (which I assume was your second/third choice) – this means that location B rejected your profile a few months ago and ‘passed’ it to location A; chances are, location B needs more consultants of your profile now…you could give it a shot by getting in touch with the recruiting team during the campus event
3. You changed your mind and now prefer location B – I am sure that the recruiting team will happily assist you on this one; be prepared to give them a good explanation/motivation

I hope this helps,

Best,

Jacopo
