I have got an interview offer from a multi-national company. Somehow I got to learn that I know the person who is going to interview me there. I mean he is not my close friend as such, but I have interacted with him couple of or quite a few times in the past. And I am very sure he is also aware that he knows me.
Question: Is it good to communicate with interviewer (on Linked-In or on Facebook etc) before interview just to build good repo? Would they take it positively?
