I would try not to judge companies like that. I had an internship at a place that was consistently rated the best place to work in the area, interesting work, great development environment, etc., but they used this source control product called AccuRev. It was this slow GUI-based thing with it's own unique vocabulary, nobody really liked it, but it was still a great place to work. If they don't use source control at all, that's obviously a problem, but don't discount a company just because they don't use your favorite software.
