Pros
None. But seriously, since Glassdoor requires at least 5 words for the Pros section, I will say that they have a very nice office building.
Cons
Every single thing about this company is one giant con. Stay away. I cannot think of enough ways to seriously warn you and not work here. Prior to CoStar acquiring Apartments in April 2014, this was the greatest company to work for. I made lifelong friends, enjoyed coming to work every day and loved my boss. CoStar has completely destroyed everything we worked so hard to create there. I've seen coworkers get belittled, had all of their responsibilities taken away and gotten laid off. I've seen beloved coworkers leave because they were so unhappy working there, including the president of Apartments that the entire company loved. The CEO of CoStar, Andy Florance, is a narcissistic jerk. It's his way or the highway. He is literally involved in every last decision, no matter how small it is. I read an article about him last year, where he says he questions the methodology Glassdoor uses in their rankings. People are literally telling him that his company is terrible to work for and that leads him to believe Glassdoor is biased, instead of actually looking at the problem. I can't tell you how many times someone has told me they literally only work there for the money. I mean good for you, you're making money while working at a morally corrupt company. Andy's response to any issue is either to sue or throw money at it. How's that for a role model? Seriously. Do just one google search on the guy and it'll be enough for you to never want to work here either.
