Recruitment standards for Harvard Business or Law are also pretty much comparable to any other school, at least on paper. You have to have an undergraduate degree and a pretty solid vita.

Who is actually applying and who is getting the place/job might be another question, though.

If you want to become a FA in Germany, Switzerland or France, you apply at the national carrier first.

If you want to become a FA in Romania, Hungary or Bulgaria, you might go to the NE3 first, maybe even to Ryanair (although in Poland LOT used to rank way above Ryanair for quite some time...)

Same story for pilots. And living in Dubai, Abu or Doha is also not really that interesting for most pilots and educated people I know in Europe. I fear the Lake Zurich or the Tegernsee is somehow superior to the Dubai River.

But, of course, there are always exceptions proving the rule.
