Pros
There are a fair number of perks that are nice, like the cafeteria and food trucks. The company itself is healthy, and anyone willing to coast along will probably do fine here.
Cons
I do not recommend working here if you have any desire to grow your software skillset. I suggest finding another place that will let you explore software programming technologies and grow technically, because you will be hard-pressed to find those opportunities here. Most of the senior engineers here are stuck with an understanding of C++ that dates back to the late 90s, and they show no interest in learning about how it has evolved since then. Those who do use C++ don't get to use anything newer than the C++11 standard. There was an initiative from staff-level engineers to not allow using C++ templates or object-oriented design patterns. There are staff-level engineers here involved in myriad decisions and designs who aren't familiar with Python. There are entire software divisions that are allergic to unit testing and CI tools. At a fundamental level, this company and its senior engineers do not care about learning and trying new things. There are problems that plague its software development cycle, and when presented with solutions that can solve these, the senior engineers and management refuse to engage with them. Worse still, management uses textbook Sunken Cost Fallacy arguments for why things shouldn't change. The CEO is a very smart person and knows a lot about a lot of different technologies, but he is not a software engineer and is not concerned with best practices. This wouldn't be a bad thing at any normal company, but Banner will take his opinions as strict guidance on how to run the software divisions. This will likely never change. There are four software groups within the company, but nearly no consistency or coordination between them. It is going to be a decade or two before the dinosaurs at Banner retire and the company can possibly move on. I don't recommend working there until then.
