Do you want a FB or a major airline job ? After you get to your career destination go ahead and get that all important FB account LoL. It might or might not cost you millions of dollars in lifetime wages and retirement if you choose wrongly. Do I think it’s a big deal? Nope but as long as your employer does so should you.
Lurk on your wife’s/brother’s/parents FB Page if the social media withdrawal is too much to bear.
