It's possible they have a bunch of tools written as emacs scripts to the point where it's become a key part of the role. There is enough of a learning curve (the editor itself, short cuts, elisp, plugins) and a significant chance that someone could quit in frustration that favoring people with experience makes sense. I like to use vim whenever possible, but my job requires Visual Studio for many day to day tasks and would not hire someone unfamiliar with Visual Studio.
