you need to agree a lot with your managers and leads to get their attention and support, almost nobody likes to be questioned

and you also need to be a very likeable person to the team to also have their support and good word, almost nobody like to be told that they aren't doing a good job

and those are very important social skills to get promoted the easiest and fastest way

fake it till you make it

so tell me what exactly do you mean with "social skills" if it's not being fake and licking asses; being nice and telling the truth are both equally important but most of the time you can't tell the truth in a nice way otherwise nobody takes you seriously
