Deciding which office to apply to

I’m applying to Bain FT and wanted to see if anyone had any advice about which office I should target?

Target: London, Madrid, or ME

London because I did my undergrad and PhD (STEM, semi-target) in England. Madrid because I’m Spanish. And ME because it’s the only place I have a strong referral (from an analyst soon to be associate)

No strong preference towards any. Ideally London of course, but I know the competition is insane, so I don’t even think they’ll consider me.

What do you guys think?
