CoStar Group reviews

Workload, unrealistic targets, constant KPI changes, wasting hours making calls just to hit a number

CoStar Group is one of the most toxic and demoralising workplaces I’ve ever encountered. The culture is controlling, outdated, and completely unsupportive. It feels like being trapped in a strict school, not a professional workplace. You’re monitored constantly, micromanaged to the extreme, and forced to hit unrealistic KPIs that change on a whim. There’s no transparency, no consistency—just pressure. What makes it worse is the complete lack of job security. People are fired without warning, no performance reviews, no opportunities to improve—just one day you’re gone. Management thrives on fear and uses it as a tactic to control staff. It’s a high-stress, high-turnover environment for a reason. The lack of diversity is glaring. Leadership is overwhelmingly homogenous, and there’s clearly a glass ceiling for ethnic minorities. Opportunities for advancement are few and far between unless you fit a certain mould. Inclusion feels like a checkbox exercise, not something the company genuinely cares about. If you’re a person of colour or from a minority background, don’t expect the same recognition or progression as your peers. Overall, CoStar may look polished from the outside, but behind closed doors, it’s a toxic, rigid, and exclusionary workplace that drains your energy and offers no real future. Avoid at all costs if you value your mental wellbeing, professional growth, or being treated with basic human respect.
