Pros
It would've been 5 stars a year ago or so but that has changed. I joined a company with top-notch engineering talent, a collaborative culture, righteous values, and the opportunity to do hard things in the robotics space. That all went away when they hired a wannabe COO with no proven experience to run the company. If you're sensitive to risk then it might be worth joining, just go in with eyes open! But if you have military background, you're safe!
Cons
The COO has been on a layoff spree since he joined. Yes, I said the COO because the CEO just lets him do as he pleases and doesn't have the heart or backbone to take hold of his company. The COO clearly bring in his cronies, throws everyone else on the scrap heap, gets rich, and is just looking for his next move.
