Pros
The product and company goals were worthwhile: teach the fundamental principles of robotics via a hardware construction kit and dedicated software. The (US-based) employees cared about producing quality product and good user experience.
Cons
The two main issues with the company were: 1) Inter-office interaction. Attitudes of the China-based offices toward the US office were poor, which was disappointing as we assumed the shared goal was to collectively produce a successful product. 2) The CEO. She often lied about product capabilities and her industry insight to participate in public speaking events. There seemed to be constant disagreement between executives on how to run the company, which eventually broke down into childish screaming matches and the release of most employees from the US office. Additionally, after my full time role ended, I did some paid consulting as a favor to the company. Like other experiences mentioned here, I never received payment for the work, although promises of payment were frequently made.
