You might get stuck on a project for a long time. I was converting Cobol to C# my whole time there and I wouldn't do it again. I rarely got to work on more interesting things and, at the time, I found those things difficult to understand.
There isn't any training, because anyone who would be able to review your code or help you is typically too busy. People are willing to help, but getting that help can be difficult in a project where you're new to all of the tech.
The 401(K) options are pretty good (quite a few options with low expense ratios), but the 1% match is not great and the 6 year vesting schedule is worse (0% vested until 2 years at 20%).
Probably common to most companies, but you'll likely get conflicting information from different people. For example, I was told by one person sick leave could not be used for appointments and another that it could.
I've heard that raises don't exist from several people who worked here for long periods of time.
Entry pay is the same whether you're from Codeup or have a 4-year degree.
Your office can be isolating. You must be a self-started in every sense.
No remote, though it has been talked about.
