Pros

Coworkers have integrity and care about the quality of their work. A lot of remote work positions. Good work/life balance.

Cons

Lack of communication to employees. Usually find out what the company is doing through LinkedIn posts. Laying off experienced employees and rehiring in low cost regions. Layoffs are not announced. Employees just disappear, unless they take the initiative to email colleagues that they are leaving.
