Pros

Great for grads Good starting salary (but don't fall into the trap of thinking you can't get it elsewhere)

Cons

For context, I didn't leave on bad terms OR with an angry mentality, I also wasn't graced with an exit interview but this doesn't bother me. Recent HR meetings with 'market managers' have been advised this by HR as an excuse for the poor working environment leading to an abundance of negative Glassdoor reviews. Note - Glassdoor reviews have been removed over the last few months. It has also recently come to light that apparently the 'market managers' have a joint WhatsApp group in direct relation to all these Glassdoor reviews where they gossip and discuss who has written what/what has been written. Shouldn't this be taken seriously rather than mocked? To all those looking at applying? Don't. To give an accurate picture of the state of the department.. 9 researchers have given in/left the company in the last month.. more in the pipeline.... the great resignation is true.. for CoStar anyway! This company has so much potential as does the research department but it's simply not executed in the way it should be. Management are bullies. Either they are terrified of their director (who in turn is terrified of their Vice President) or put simply a complete sociopath.You will be forced into a corner to make your manager look successful but they will be the first to turn on you if something doesn't work for them. CoStar brings out the worst in the managers. Working from home was great. We could get back some additional hours from travelling which would normally be wasted crying yourself to sleep each night. As previously mentioned the return to office was declared for September but in no capacity was it explained how it was going to look in till 4 days later. Attempting to coax us back in with sushi and pizza really didn't do the trick when we have to be faced with the daily misery of the office. Why don't you leave you ask? CoStar makes you feel worthless, incompetent and unworthy of doing any other job. Your confidence is slowly chipped away of the time you spend being gaslighted by your manager. The researchers/CRC's are far more valuable then the 'Managers' who are actually glorified auditors who barely do any work.

Cons

Working at CoStar Group was one of the most emotionally exhausting sales environments I’ve experienced. The culture on my team was extremely male-dominated, hyper-competitive, and very much “sink or swim.” Collaboration was talked about constantly by management, but in reality the environment rewarded internal competition, territorial behavior, favoritism, and politics over actual teamwork. As one of the few women on the sales team, I often felt isolated and unsupported. Instead of mentorship or coaching, the expectation was basically: “figure it out yourself.” New hires were thrown into difficult situations with inconsistent training and unrealistic expectations, while certain reps appeared to receive stronger books of business, better territories, or more support than others. It created resentment and a toxic atmosphere where coworkers often felt more like competitors waiting for you to fail than teammates. The turnover was incredibly high, which should have been a red flag. Management pushed aggressive quotas and nonstop pressure while failing to address morale, burnout, or fairness concerns. There was also an unhealthy obsession with leaderboard culture and internal politics that made the workplace feel stressful every single day. What disappointed me most was that I genuinely believed in the product and enjoyed helping clients. Many customers loved working with me, and I built strong relationships. But internally, the environment became mentally draining. The constant competitiveness, lack of support, and toxic culture eventually outweighed the positives of the role.
