Pros
For learning the skills in a sales role, you can make decent commission but this will stagnate after a couple years. You can basically do what you want since there is no supervision and there is no system in place for accountability. I usually wrapped up "work "by 10AM and looked at other jobs or earned some extra money tutoring students online. Super easy gig.
Cons
CEO routinely has a quick temper and will be your buddy one day, then will ignore you for weeks or months at a time without notice. After getting to know him, I realized he was doing me a favor, so I generally preferred it when he would scowl at me and slam his door shut without a word. To his credit, for a thin-skinned introvert with outdated ideas and a fragile ego, his moderate success is astonishing. The work is not challenging at all but their filtration systems leak so you will have practice handling angry customers. Hit it and quit it!
