Pros

They give a lot of swag, work pace isn’t too hard, mid level people are generally nice

Cons

This company ruined my life and PIP’d me for taking time off to mourn. They took from me my passion for what I do and made me realize how quickly someone will throw you under a bus. Scheming managers. They did a soft layoff where they were forced to PIP a certain number of employees, I had never had a performance conversation or a negative comment and the manager fabricated evidence for a pip (including asking for advice, taking sick time when my dad died, and calling in a senior engineer during a high severity outage). I’ve personally spoken to multiple other engineers that had the exact same thing happen to them.
