Pros
The topics are very interesting and you get to see what large corporates do with regards to circular economy
Cons
A large deal of the projects is just involved with marketing talks, and it's always the same people talking
Even though all people at Circle Economy are super enthousiastic and motivated about the work, it's hard to work your way up. The company is still small and middle management is all being attracted from outside. Even if you make very clear you're interested in contributing more, they just won't always let you, which is strange as there's more work than people.
Furthermore, it has a lot of the usual start-up issues, so a lot of stuff is very disorganized and a bit amateuristic
