Pros
None of the senior leadership are founders, which means there is less sentimentality and emotional attachment to "how things started". This means the environment is super dynamic and the leaders are not afraid to make difficult decisions. It's not a bean bags and fancy coffee machine type of place, instead you are rewarded through having really interesting responsibilities and getting paid a proper salary. (Apparently somebody is looking into upgrading the coffee machine as well though...) Really nice office in very nice location. Well founded.
Cons
Fast tempo and pressure that comes from having interesting responsibilities with a lot of individual autonomy. The team is somewhat male orientated, but it seems like leadership are trying hard to diversify.
