I can't speak to some of the options here, but I wanted to let you know to at least
keep your options open. If you focus on ESCP, but are not selected there, you would have no other options.
Investigate your other options. Look at these programs and what they output (i.e. who their graduates work for). Also consider places to live (you may prefer a city in the south over a city in the north just because of i.e. weather.
Also, more interviews are a good thing - they train you in interview skills, which you need to get a job in the financial world anyway.
Focus on ESCP, but do your research on the others. Maybe drop one - the one you like the least - and go from there!
Good luck!
