Completely am on-board with the descriptions of false positive&#x2F;negative<p>I agree that this seems like a good way to establish someone&#x27;s technical competence.  I do wonder though from the interviewee&#x27;s side what the optimal time to spend on one person is.  It&#x27;s kind of like dating right? (Well what I imagine dating would be like if I lived in a big city)  You have concurrent first impressions with maybe second and third follow ups before you seal the deal.  This may be a bit like asking for a relationship on the first date.<p>Demonstrating ability in this manner works for more junior people who maybe don&#x27;t have a github or other personal projects, but I&#x27;d consider discussing and reviewing those more valuable.
