Pros
This place is one of those example companies one needs to experience in their lifetime to gain wisdom and discover that this is not how a business should operate and who NOT to be. Owner is super chummy during his interview with you and when offering a job, but turns around and treats you like his slaved peon soon after you're in. A job not for the long term, nor for the faint of heart. You gain experience and learn to be a better person in whatever career field..sales, marketing, IT. A stepping stone to something far better.
Cons
The owner promises sales people a monthly recurring revenue for contracts you bring in but within 3 months or less, he'll let you go, taking the business you bring in, so he doesn't have to pay the commission he initially promised.
