Pros
A few colleagues are authentic If you are starting in the field and ever felt curious how IT companies rocked it in 2007 this is your place.
Cons
Lower salary than the average They are proud of the flat hierarchies but in reality you will be managed by a lot of people If you are friends with the "key" person in the company your career will sky rocket, this is, a CTO, an specific Swe/Fin manager and a few legacy developers They will justify people not moving forward in their careers, i.e. not having a higher salary with people happy in their current position and voluntarily not engaging a higher challenge Drupal was, is and will be the main business, forget to work with anything else You need to constantly watch your back If you are a female you might have even a lower salary
