For what it's worth, I kinda like the idea. I don't think coding interviews are going to go away anytime soon and I'd much rather use HackRank's fancy interface from the comfort of my home than stand awkwardly at a white board while one or two people stare judgingly at the back of my head.

Despite the somewhat sensationalist headline, the article itself actually seems to be pretty realistic (aside from the "and in a year from now, HackerRank will be like that" comment).

To me, it seems like another tool people who are not good at networking can use to distinguish themselves.
