Pros
By far LinkedIn has exceeded my expectations in every way. I was hired through an acquisition, and they made every effort to make us feel comfortable, and allowed us to continue working on our products. The culture is great, very empowering, a lot of perks, a focus on true leadership from managers. Every LinkedIn employee is smart, collaborative, and easy going. I love coming to work every day knowing my colleagues are bringing their A-game with no drama. The leadership is awesome, and they take their cultural values seriously- they aren't just motivational posters on the wall. Also Jeff. I'm just an IC, but Jeff is the kind of leader everyone wants to follow. The vision he sets for the company is big enough, and the empowerment cascades from above. He delivers his communications with transparency and authenticity. Even at the IC level, I can see how my work relates to our mission.
Cons
Typical big company problems, knowing who to talk to, being proactive on finding the right stakeholders for various product lines can be difficult. There is a lot of movement between the three campuses to collaborate, so it can be weird on your schedule.
