Pros
LinkedIn values their employees and you experience that through beautiful facilities, food, perks, and benefits (half the cost of my prior and current companies, both of which are great). Budget is allocated so managers can do a team building activity each month, and travel is easily had when needed. There's also a big focus on personal development, and I did transform as a leader while I was there, taking advantage of in person and virtual training, speaker series, and learning from managers and senior leaders.
Cons
After several years at LinkedIn I started to see the ugly side for what it was. I saw how e-staff seem "amazing" in front of a crowd but are often arrogant jerks if you actually have to work with them. People cower around senior leaders trying to keep them happy and there is a lot of deferring to the most senior person in the room. I also saw good people get pushed out and overly-political and ruthless people get promoted (though I say that having been promoted twice while there LOL). When I left it had become way too bureaucratic, too political, and too fearful (crouching in a protective position vs. innovating and actually "taking intelligent risks"). Also don't join LinkedIn unless you love meetings - the company value of "Collaboration" means no one is empowered to make a decision until you get a dozen people on board, requiring 30 meetings to get there. It can be collaboration at its worst. Overall I'm grateful to have had the experience, but am glad to have shaken that cult-like LinkedIn-worshiping mindset.
