They’re not your friends, even if they act like that.
The management just sees you as expense factor and does not care about you except for how to get the most work done for the least amount of money. Your team leader does not care about you and only cares if their numbers look good. Your colleagues do not care about you and only see you as competition or the idiot they can give their work to.
If someone is nice to you they want something from you not because they like you.
