If someone has worked as a software engineer for more than 6 months, that someone already knows how to "use IDEs" and version control.
Are you serious? I'm continually saddened by how many software people I run in to that do not know either one. FTP and Notepad++ are their 'tools of choice', and that's it.
About half the developers I know are using modern tooling (version control, IDEs, virtual machines images, testing tools, etc). The other half are very much in the 'ftp/notepad++' or maybe 'sublime text' camp.
Trying to convince people that they should be using version control even if they're the only developer on a project is usually like swimming through molasses.
I use vim very much by choice. I'm not ignorant to what IDEs are and do, but I choose vim instead. I use version control. I use virtualization (with Vagrantfile for getting my development environment up) and I write tests with good coverage.
But because I use vim I get lumped in with people who never use version control?
It's surprising how many people don't use source control, but they do tend to work in smaller shops (one or two developers) or places with little change.
