Indeed, I've always been against filtering people on programming language. However, I wouldn't hire a developer that wasn't good at the language they had been using or learning for the last years. In the same way, I wouldn't stop from hiring someone without git experience. But I would definitely not hire someone who, in 2024, hadn't been using some CVS tool. Plus, I would be curious to know how the applicant had been sharing code with colleagues in group projects and why they had gone for solutions other than git. For someone more experienced I would be wondering how they managed to be insulated from the most widely used code repositories like GitHub, GitLab, BitBucket, and so on, which overwhelmingly are git focused (BitBucket even started out as a Mercurial solution and then slowly shifted to Git). This could actually be an interesting window into the applicant's decision making process. Even though I would be open minded, I think that the odds would tend more for me to find out reasons not to hire that applicant.
