Pros

Health insurance and other perks are competitive for the industry.

Cons

- Terrible company culture. The environment feels toxic, with little trust between leadership and employees. - Mandatory 5-day RTO. No flexibility — even roles that could easily be done remotely are forced into the office full-time. - Micromanagement at every level. You’re constantly monitored.
