Pros
The only good thing I can say about CoStar is the people. The employees in my department are largely very nice. Salary can be good in certain departments but it is not worth it.
Kontras
There is ZERO work-life balance. Leadership does not care about the physical or mental health of the workers. The health insurance is a wild pain. It took 2 months to get a pretty basic procedure approved. They will make you take hourly PTO to pick up your child. If you get Covid, you have to take sick days (which are limited) instead of letting people work from home, even though there are many remote employees company wide. There are weekly metrics for my department that are almost unattainable without working a minimum of 50-60 hours. Things change almost daily and mostly never for the better. Communication is lacking which causes a lot of widespread confusion. The systems we work with are broken and there does not seem to be any fixes in sight. All around just a bad place to work. 10/10 do not recommend.
