Pluspunten
Some very talented, very nice people. All depends on the group you're in. Pleasant physical environment. Good pay, including bonuses.
Minpunten
If you're in one of the not-so-good groups, it is like living in a tribe of primitives from 10,000 B.C. Strong personalities set the direction. Whoever yells loudest, throws the most effective tantrum, or interrupts the most, that's who sets direction. Managers talk smack about other employees during your 1:1 (backstabbing anyone?). It feels like middle school with the people who suck up to the manager getting the promotions. Anyone who thinks for himself is shunned. Individual contributors are simultaneously told to "think for yourself" and "follow the conventions". Managers meddle in individual contributor work while ignoring their own managerial work. Performance reviews are late and without constructive input. No one knows why they got the bonus (or lack of) they got. Abuse of manager power can be epic.
