Pros

Good pay. very generous with expenses. No micro managing.

Cons

99% prospecting, high pressure to achieve sales target, hard product to sell because of the price, and REVERSAL , if the client decides to not renew his contract for another year, they take back the commission. Even after 10 years of them being a client. if they end up not renewing , you get deducted that from your commission.

Pros

My experience has been very positive at Costar over the last 8 years with consistent career advancement and opportunities to collaborate across functions and with senior leadership. Execs and senior leaders are very accessible, and while this may not be the most popular view by others,I find the full-time in-office work the reason for these collaborations and advancements.

Cons

Confirming what everyone already says about Costar. There’s just no slacking. You have to be present, engaged and put in effort. Those who want to do bare minimum will struggle and those who want WFH won’t find the success as so much of the work relies on interaction and support across functions
