I was considering interviewing at Facebook. I am not sure if it is worth the effort though? I am in my late 40s.What is it like to work at Facebook at this stage of my career? I am presently a very senior engineer and work on r&d projects including new product development as well as presenting at conferences and writing articles on our advances.While Facebook may pay much better, would I be throwing away a pretty good job just to be paid a ton but work at a much lower level? Is it not Facebook’s strategy to “overhire” in the sense of putting extremely qualified people on what would generally be considered menial tasks?And what about age discrimination and work/life balance? Do people last at Facebook for longer than a few years? Are parenting and family responsibilities honored?
