Vantaggi
If you are in your 20s, the salary is pretty good at a base of 40k and the benefits are extensive. It is also a great resume builder, especially if you want a career in real estate and research.
Svantaggi
In essence, your performance is often measured by those who have never performed your job and the metrics not only have little to do with providing valuable information to the clients you work for, but creates unintended consequences and moral hazard that leads to the opposite of your intended responsibilities. My former coworker (who quit after 1 year) said it best, at CoStar they expect you to look left and right at the same time. Beyond the work being repetitive, the management is deplorable. I've only known 1 person who has come to like the job during my year of employment and the vast majority are constantly seeking employment else where.
