Pros
Eh, people are nice i guess. but really, there are not many pros. This company will not have a future, and their acquisition was the beginning of an end.
Cons
Literally a death magnet for a software engineer. Their tech stack, wtf? no applications in real industry. Their development process? pretty sure its just write a bunch of code and deploy when you feel like it. no product managers, no structure, no real future plans for expanding the product. in fact, their tech is so isolated and unlike anything else in the software engineering world (not in a good way) that i don't think they use a single piece of open source software. that might sound cool, no dependencies is a pretty good thing, but not when you find yourself reinventing the wheel for every tool that a good software engineer relies on. bottom line, this is where your career dies if you go here for software engineering.
