Pros
Really kind people work here, for the most part everyone I have worked with is smart and I have learned so much from them. There are great benefits: unlimited PTO, 6 week paid sabbatical is earned after 4 years of employment, 6 month maternity leave. Great location of an office. Great work life balance.
Cons
Not very competitive pay and it is easy to hit a ceiling in your career development. New HR policies are kind of strange, will not promote you unless you make enough money to be promoted which they designed the system to make it so you cannot go up. HR has also laid people off because they make too much money without considering the consequences of removing senior employees with unique/not stored intelligence vital to the company. They also hired a bunch of remote employees, then implemented a 4 day required in office rule no matter if you live states away from an office, which pushed hundreds of people to quit, not receive their bonus, and not require M* to pay them severance. It didn't use to be this way but the last year or so has been strange.
