Pros
Colleagues (non management) are very nice, helpful, supportive. Would have been a great team if not most people left.
Cons
Most knowledgeable colleagues have left the company. The company lacks good leadership, good treatment of employees and communication is really, really bad. They lack concrete vision and the required technical understanding of what they want to achieve, switch direction every ~6 months, refuse to listen to their engineers and scientists - both regarding short-term projects and long-term directions, and appreciation is non-existent. There's no product and there never was one, because they never had the patience to become superior in one field. Hence, no stable income and they live from research funds + some investments and wasted money due to tons of mistakes - large and small, but still they refuse to learn as there's zero self-reflection and retrospectives across decision makers. They would are good at selling dreams, the informal motto among employees is: over promise and under achieve. If you want to waste your lifetime in a hamster wheel rushing down the abyss - be ready to hit the ground and not being paid in the end. So, do yourself a favor and look for alternatives - it's not difficult to find a better one, basically any company should do.
