Pros
Food is great. Coworkers are nice. Everyone is laid back.
Cons
I am doing intern in Banco Santander for almost one year and I am leaving. Basically all interns have to do the same amount of work as full-time employees but with a salary of monkey. Your efforts will not be appreciated in this sinking boat no matter how hard you try. At least in my department, managers do no truly communicate with anyone and basically they are all well-paid politicians who will never tell you their true feelings and you cannot count on them to give you any sincere career advice. This might not be true, but it seems that all they want is to take advantage of the cheap labor and they cannot care less about people. People come and go all the time and turnover is surprisingly high. I strongly do not recommend those ambitious, those down-to-earth, and those getting hands dirty type getting on the boat.
