Pros
LinkedIn has great benefits including free meals, snacks/drinks, commuter shuttles and unlimited vacation. There are opportunities for growth and the environment is very dynamic, so there a no shortages of interesting challenges. Most of my interactions with other team members were very positive.
Cons
After being acquired by Microsoft, most all communication and some productivity tools were replaced with Microsoft-based solutions that are less useful and less reliable than previous tools. Issues/concerns taken to management aren't taken seriously unless the resignation card is played. Team management kept too busy with other responsibilities for a reliable 1:1 meeting schedule. Promotion process is too similar to a popularity contest. Team/management structure setup in an odd way that lead to stress and confusion.
