The job is not advertised correctly. It is a sales position with a baseline compensation of $40,000, which comes out to about $2,400 per month after taxes in the grand state of Massachusetts. Hardly the $60,000 "total annual compensation" that the company advertises in its job postings. Unreasonable sales targets for associates mean that most people don't get sufficient bonuses to make up the gap between what is advertised and the reality. It wouldn't be the end of the world to advertise the position as $50,000 to start with lots of promotion & commission opportunities (which is the industry average, anyway). Folks would still apply...
Mosaic is a middleman for institutional investors that don't want to bother themselves with finding industry experts when they can just outsource that task. As an associate, you are responsible for finding the contact information of individuals who can speak about specific industries. Then, you reach out to/harass them until they get on the phone with you, at which point you ask if they'd be interested in speaking with your client. That's it.
It's pretty repetitive and boring work, especially if you don't try to amuse yourself by taking an active interest in learning about the different industries. You don't learn any hard skills since there is no professional-level training in any of the platforms Mosaic uses. Also, too much micromanagement - even people higher up the food chain don't have much autonomy.
Other cons: high turnover, hothead CEO
