London vs Frankfurt for MBB

Thats a lot of questions, so I'll do bullet points

• Visa
  • All MBB sponsor indiscriminately, so no. Don't know about RB (I assume they would sponsor too)
• Recruiting for London
  • On the MBB websites, just state London as your preferred office with a decent % allocation for it (they each should prompt you for 3 or so office choices, with a weighting that has to add up to 100%)
• Chance?
  • No idea what your profile is, but obviously a regional school will have more weight in said region. That being said, don't know many Dutch-educated people at Bain London, LinkedIn might be your friend there to check RSM's placement in London. If you have >10 in an office, I'd say you're fine (difficult to generalise as self selection will play a role)
  • That being said, Bain London does not do interns other than MBA interns (I believe McK and BCG do, so they might be better in that regard)
• Spring weeks
  • We (Bain) don't, but I think McK do. Don't know about BCG
• UK vs DE Principal/Partner comp
  • No idea, but the difference will be so small as to make no difference (cost of living will be the big differentiator)
  • Also, does not matter since (1) very unlikely you'd stay that long, whether you get pushed out or choose another exit, (2) at that level it absolutely will not matter, and (3) you can't predict how exchange rates + fiscal policy will move in the next 10+ years, the likely amount of time it would take you to make it to Partner, and how it would impact the relative levels
• PE
  • Common sense says that London would be better, but if you're going to be in mainland Europe, then DACH is defiintely the right place to be (rather active region for deals)
• MBB vs IB
  • Hard to answer as I have no idea what your plans are, what you consider "losing" or "gaining", or what your personal preference is
  • I will say this though: if after you start practicing case interviews and start getting good at them you still don't enjoy caseing, then consulting is probbaly not for you (the job is a lot like that, magnified)
  • Also if you prefer a career in finance (IB/PE/VC/HF) then obvs IB is way better for that, MBB is fine but it will be harder to jump (though far from impossible), the upside will be more varied exits (so up to your own preferences)
