Pros
No need for an engineering degree because the "CEO" has a marketing degree but could have "gotten a full scholarship for engineering" if he wanted to. Comradery over hating your boss and constantly making fun of how this was never going to work but doing it anyways. If your a desperate college grad it's experience that you can put on a resume, don't expect to learn much unless you take the initiative.
Cons
Within the first month I was searching for another job. Forced to drive to Colorado and set up a prototype that we had just managed to get working the week before made from plywood and metal plates. Dangerous environment working next to RF with no safety equipment, high energy and open dryers. Then having to lie to customers when the CEO overpromised what we could deliver but the check had already been cashed. A Ponzi scheme in the simplest form. After Colorado it was a revolving door of "over 50 products" that all had varying chemical make up and drying behavior. This was only done to collect the small fee we charged to "analyze" the material. But don't expect to spend your time figuring out how to dry products. Instead spend your time loading, unloading, and driving the tons of corn and soybeans to the poorly situated facility and loading the material into supersacks to rot and spray up huge amounts of dust. The pay was barely enough to live off of and the promises of "bonuses and shares of the company" were always delayed for one reason or another. He will hire you as an "intern" to pay you the least amount possible then never bring you on full time. Expects you to do all the work and then take the credit with no compensation. I still remember when I got my offer for my next job, best day there.
