Pros
Yes, I second a lot of the previous reviews, the benefits, pay and amenities are a big perk. More importantly, CoStar is a company that never settles. They strive to be the best in everything they do and will turn on a dime to change and make an impact where it is needed. In most cases, the research position is your start with CoStar. If you do your job well and professionally you will have ample opportunity to move up or into other positions inside the company (managers, analyst, CRMs, recruiters, sales, training, etc). A lot of the management consists of tenured CoStar employees and industry experts. The company is also generous with money when it comes to its performing employees. For employees that are underperforming in their roll, there is always a pathway to help them out. The culture is another big plus. Overall I enjoy working in a self motivating culture with a lot of hard working individuals around me!
Cons
CoStar is a 30 year old company, that at times will work like a start up. Expect to work hard but with great reward. You will always have your plate full and that is not necessarily a bad thing. In fact, your days go by quicker this way. It is much better than starring at a clock.
