Most programming happens in a team environment. It can be difficult to separate the impact of a good programmer from a substandard programmer in a good team. GitHub and code samples can be useful, but not every candidate will have shared code on GitHub (in fact, most don’t) and retaining copies of code they’ve written for a previous employer is a major red flag. The biggest issue with using prior experience is that it’s hard to compare the ability of programmers who work in different languages and different domains, it can be like comparing apples and oranges.
