Vantaggi
While I worked there, it was actually a great experience. My responsibilities were reasonable, my workmates were fun and engaging people, and I never felt stressed out while at work there.
Svantaggi
There was apparently some drama between the US-based boss and the Poland-based CEO of the company. While I don't really know the details, it culminated in the entire Fibaro USA branch being shut down and all its employees being laid off. It was highly dissatisfying to be working on launching Fibaro in the US and being shut down before launch.
