Pros

Nice coworkers and salary is decent

Cons

This is falsely advertised as a 'market research' role, when in fact the role consists primarily of cold calling brokers who want nothing to do with you and asking them nonsensical questions. CoStar's entire business strategy is annoying these brokers into providing information and then selling the same information back to them. I mean, if it works it works? This role comes with the insane micromanagement typical of all call centres. I was less supervised as a high schooler than I was in this role. Prepare to have all of your stats shared to the teams chat, where if you're unlucky enough to not have any of your calls answered, your name will be highlighted in bright red for the entire office to see. I would work at this company only if I had zero professional experience and needed the money and something to put on my CV. Anyone else is automatically insanely overqualified for the role. It's quite dystopian to see an office of intelligent people, some of them having Masters and +10 years in the industry, making cold calls for the purpose of meeting useless metrics.

Pros

Really cool product with an interesting client base

Cons

In today’s world, any perk they offer is subpar. No flexibility in your life, toxic culture, and only a few people in each market are set up for success.
