My previous company had what I think was a good hiring process: they required about 500 lines of Python code (it was a mainly django shop), and if your code was good, they'd ask you to go there one morning/afternoon and implement some minor feature in the development codebase. For frontenders, the process was similar, but they'd ask you for some mix of JS/HTML/CSS. The 500 was a somewhat arbitrary number, but it was basically "show us a good amount of what you have done". In my personal case, I sent them a link to one of my python libs in github, but some people without github sent some files like headers and implementation (like one or two guys for a ObjC role). If you passed the initial code review, survived the day with the team, they would still ask for one or two contacts of previous co-workers, teachers, etc., just to have a chat. In the end, we had a very very good team there!
