Pros
Flat structure, low level of mgmt control that invites and motivates for bringing your own ideas to the table, and actively take part in development process of different projects. You will instantly be welcomed into the company's very warm and open culture - whether you're the new intern or sales director! Designit will further try to get the optimum from your set of competencies, so you will get room for developing in many areas and trying out different tasks. Besides, on the social level, Designit is a great place to work - 2 annual company trips abroad for all Designit offices, and parties as well as inspiration sessions almost on a weekly basis.
Cons
Generally, I haven't had any negative experiences working with Designit as an intern and later as a student employee.
