Pros

Package ok. Peers are good.

Cons

In my opinion some of the senior management should be ousted. They micromanage, are toxic, narsasstic, and not team players. Complaints to HR fall on deaf ears...even formal complaints!!

Work from home, small team, multidisciplinary

Mostly contract work, very large business so you may get lost in the shuffle, the usual hyper competitive professionals can make the environment stressful
