Created a second account because HN says I was submitting too fast (no wonder there are no interesting AMAs on here).

I am all for a generic "Link to your code" field on a job application form but also provide an alternative like "Is your code not public? Send us an invite to your repository or send us a zip of some work that you are proud of". I am okay with that, I did this for a job application that required a Codility test which I didn't do. I am not saying that I am unwilling to give you my code, but for the sake of a job application it does not have to be open to the world. I agree that Github still has benefits for recruiters but they should not become blinded by it thinking it is the only platform where developers can showcase their code.
