No, they're merely a technical fit, maybe, depending on what you ask. (Your blinding process would also mean preventing interviewers from seeing any open source contributions which may be far more indicative of technical fit than anything you'd ask in an interview.) Technical fit might be enough for most roles, more blinding at least at the initial filtering stages might be a good idea, but culture fit is important for a lot of firms. At the very least people will want person-to-person interviews to maximize their odds at detecting a permanent asshole (and other toxic types), since typically no one wants to work with one even if they're skilled.
