My 2 cents. The major difference first of all is location. Wherever you do your MBA from, you’d want to cash in that MBA in that very location for next 6/7 years, perhaps for the rest of your life. That said - major differences are - pedigree of companies recruiting (since tech is more HQed outside India), colleges outside India and especially European are 30/40% more expensive than ISB but their avg pay is higher than fee, from an ROI standpoint - they’re better, European colleges / recruiters again have lesser hiring bias since visa rules are flexible (unlike US), also the cohort is more diverse than ISB / IIMs - from what I’ve understood - you truly get a very diverse and rich experience, also the Cohort has more work experience and are more mature unlike Indian B schools
