Hello guys!
Thanks for your replies so far! I think it would be useful to share my school visits with you and the big surprises of my after-trip
Wharton-Lauder: I had the opportunity to visit Wharton (not for Welcome Weekend though)and it was a great visit! I have to admit there were a lot of douchebags between first and second years. However, since the class size is so big I definitely found great people too. The Latin American club is amazing (very down to earth too).
I would put it this way: 50% shallow | 20% mix of shallow and down to earth | 20% down to earth | 10% amazing classmates. But hey, since it is a big class 30% of 800 = 240, almost the class size of Berkeley!
MIT Sloan: To put it simple, amazing student body and dissapointing Adcom members. Boston is a nice city but most international students live on-campus in Cambridge.
Also, most of Latin americans were married so it definitely changes the social atmosphere (I dont care too much about this point because I usually dont go to parties anyway).
I want to elaborate a little bit more why I think some members of the Adcom of MIT Sloan really dissapointed me:
First, after mi vist I kindly asked for a fellowship reconsideration explaining the offers from the other schools. I did not receive any reply (not even an acknowledgment of receipt).
A week later I send this lady another e-mail to ask for a confirmation of receipt of my first message, I got no response either. Later I call her and left her a voicemail about it, no response either.
Since MIT Sloan deposit deadline is March 3rd I e-mailed another Adcom to ask for a deposit extension (I have read in many forums last year that MIT did extend the acceptance offer up to 6 weeks in some cases without problem). I received a quick reply with a "we cannot extend your offer but call us to talk about your doubts".
Then today I call the admission office to ask about the deposit and my fellowship reconsideration petition: no one available to talk. I explained my situation to the secretary and she told me to write the financial aid lady again copying the admission team general e-mail.
Result: I wrote her an e-mail (CCing the admit email address) asking if she could offer me an answer prior to paying the deposit or if the decision would take more time I was willing to pay the deposit and wait for a final decision on my petition. I got an answer within 2 minutes................ YES, 2 MINUTES..... after waiting for a reply for 15 days.
The answer was: "Thanks for your emails. Unfortunately we will not be abel to offer you a fellowship award at this time" (typo included, she could not type it faster I guess...).
What a total deception MIT Sloan. I am not dissapointed of not receiving a fellowship, I was expecting that outcome already (given Sloan reputation of giving very few scholarships). I am dissapointed of the way you treated me, was it too difficult to write a quick "thanks for your e-mail, we will consider your petition and get back to you"?.
Yale: Unfortunately could not visit
Duke: Unfortunately could not visit
Berkeley: I got accepted to Haas! (got the answer after creating this topic). I visited the campus

Great student body but very small campus and most students live on Berkeley and not San Francisco (best city in US by far).
The Berkeley Adcom is hands down the best team ever. I applied to scholarships in wave 1 and I did not receive any help

However, I still think the Haas Adcom is great and the most welcoming and sincere of all the schools I visited.
Final decision: I have not taken it yet, I paid the Wharton deposit to have more time to think. MIT Sloan was my top choice as noted in my previous posts but the interactions with the Adcom definitely decreased my interest in that school.
