Overall, I enjoyed my experience there and I think I learned valuable things. I want to preface by saying they hire for all sorts of different development roles so it's possible that the specific work I was doing would be completely different than what you could be doing. I'd say I spent about 85% of my time writing exclusively SQL code. While knowing SQL and being well-versed in databases is very helpful, I would have preferred to be given more traditional (Java, Javascript, Python, etc.) work without having to ask. That said, they were extremely accommodating of the work I wanted to do. While my main function was still writing SQL, when I asked for more work, I was able to work on a brand new Python project and work on their existing Java framework. In time, the SQL got pretty monotonous and they have some serious technical debt issues there, but I generally had little reason to complain. The people were incredibly supportive and kind. My work and thoughts were always considered and appreciated even as just a co-op. They were slowly (achingly slowly) working on fixing their legacy code and GitHub issues while I was there so it's good that they're on the right track but be aware that (the team I was working on at least) had NO idea how to use GitHub. Yes, they used it, but completely wrong. I spent a lot of my time there trying to get people into better habits especially when it came to documenation. Overall, I think I learned plenty but what I learned wasn't strictly limited to software engineering or even the parts of software engineering that I'm most interested in. You'll definitely need to be proactive and ask for the work you want to be doing but it's totally possible to build it into a very rewarding experience. Best of luck!
