Pros

- No organization in org structure, can move around if you do well - No one is working, so if you work, you get promoted

Cons

- Genuinely awful management styles from some of the most senior people at the company - Horrifying HR, inhuman and cowardly - I wouldn't recommend anyone I know or love to work here. It's made up of lies and deception from some of the nastiest people I've ever known

Supportive management but cross-team interactions lacking

Pros

+ Supportive management + Somehat of a “family feel” environment for most staff + Clear guidance

Cons

- A lot of younger new starters who don’t interact as much with older staff from other departments. Cross team considerations? - Current work load fluctuates last minute
