Pros
Core values are consistent and adopted across the entire company. Everyone can recite most of the LinkedIn values by heart. The Executive Leadership team is extremely transparent and inspiring. The company is filled with smart people who are striving to build a top-notch product. And don't forget the endless perks. Employees are treated very well. Free breakfast/lunch/dinner at cafeterias that are comparable to high quality restaurants. Even the break-rooms are stocked with healthy snacks. Free shuttle from SF. No paycheck deductions for medical/dental/vision. One day a month reserved for side projects/volunteer activities. I can go on and on. The pride just oozes out of each and every employee.
Cons
401K match wasn't the best. A load of talent has departed within the last couple of years (old-timers who's stock options have fully vested), which can potentially impact the culture. Can be a little cut-throat due to "stack ranking" system, but it also promotes healthy competition.
