Pluspunten
Benefits are more generous than other firms, free food all the time, pretty office, parties and social committee. The only real possibilities of career growth are if you are willing to move abroad.
Minpunten
Too much overtime, no work-personal life balance, there is no support and services (no IT, no HR, no Administrative assistant, office facilities and marketing are bullies, you do everything yourself or you wait...), the pay is way less than competition... If you are not British you will feel the discrimination when it's time to be promoted. Same if you dare to speak you mind. Promotions are not for the most talented, creative and innovative staff, it's for the boss favorites and the Arup's followers... that don't disrupt anything.
