Hi!
I can probably share my two cents on this as I was in a similar boat about a year ago - Well, sort of, as I was weighing some US schools admits (mainly Ross, Cornell and Georgetown) vs. IESE.
However, this is where things got tricky for me. It was the start of COVID and the two things I did not want to compromise on were the diversity ratio (international to domestic) and the in-person experience. IESE offered them both and had a rank advantage. Having said this, the rankings are never the end all be all. Which is why the international mobility (something I was very big on AND is a hidden column in the rankings) swayed me - IESE was amongst the top 10 schools here and most US schools lie very low wrt this.
Regarding your predicament, you are definitely spoilt for choice! And I do echo bb's point of seeing the short-term (with your goal to get a job/internship) and the long term to be an entrepreneur (with a focus on fintech), in equal light. While I personally do know that ESADE has a good entrepreneurship lab, IESE has a robust SEE program (Summer Entrepreneurship Experience) - where you get to start your company in lieu of an internship and have the opportunity to get mentored by industry experts. Where both schools are equal is their connect with the BCN startup network. Both have deep roots and there is no clear winner there.
Regarding recruiting, I wouldn't sugar coat it but it's been abysmal globally and might spill over to early next year as well (hopefully not more). HEC, ESADE, IESE, US schools. Everyone has seen a slump. And if you'd like to take a punt on JUST entrepreneurship right after the MBA, then factors such as the cost of attendance and alumni entrepreneurial tendencies will kick in. However, if you are eager to have a job (minds change very fast when you get to the MBA
) and start something of your own, then 100% look at the latest recruitment figures and you will find a disposition by firms to focus on the rankings (ergo student pool/quality) more.
And don't worry about the language, you'll pick it up in no time. I didn't speak of lick of Spanish but you can sign up for optional classes and your Spanish classmates will help you polish your Spanish off!
Lastly, if you have admits to all these schools, start engaging with the admissions offices and the regional business clubs to ask them some tough questions about jobs, funding (for your venture someday), alumni pedigree, scholarships, etc.
Don't let up with the questioning till you're not 100% satisfied! It's a huge decision in your life, do it wisely
In any case, if you do choose IESE, the first round is on me!
Cheers!
A
