Avantages
Linkedin is a great place to work and start a career. There's a lot of opportunities for training and personal development, plus the perks are great. Also, you'll be surrounded by great peers from all over the world who will help you grow as a person.
Inconvénients
Terrible low and middle management. There are a lot of people who were there early and now have become manager who do not have a clue of how to manage. They just ask for forecasts and look up for their own interests. This causes a situation of bad mentorship and a lack of career paths. Also, there's a lot of over promising about things that will never happen. There are also a lot of internal politics and you have to be careful who you befriend if you want to really progress. I saw a lot of people getting promoted not on their merits but on who they were friends with.
