Disclaimer: I have not gone to ESMT and congrats on your admit.
I can mention that pandemic has been hard on many and it is not super fair to judge a school one way or another per see as they are subject to different mandates from the local government and the university (e.g. Cambridge mandated online for everyone and the school had to fight to go to in person or hybrid). It is also a tough topic for some of the students to discuss since they got punched in the face and you are now asking them if it hurt.... of course it did... and they can't really answer about how much gets lost in the process if they did not go school pre pandemic.... so they can only guess and what they tell you will be subjective.
What I am saying I guess is that you need a better question
