I wonder if he didn't like you because you didn't look like a hipster.... I'm totally serious: I really wonder how many of these baffling interview experiences where seemingly highly-qualified candidates get turned down is really about non-technical and non-work-related factors, but no one wants to actually admit it. How much of it is due to personal biases by the interviewers, who may discriminate against people for various reasons? A lot of people want to surround themselves with people just like themselves, so if you have a company full of hipsters wearing fedoras and someone comes in for an interview and they don't look like that, they could easily be passed over because they're "not a fit for our company culture". I don't think I'm half as competent as the guy who wrote this article, but I've had a much easier time getting jobs in general. My background isn't even CS, it's EE, so I totally suck at all the algorithm questions. But OTOH I generally apply for embedded programming positions where knowledge of algorithms isn't that important anyway. I even interviewed at Google (one of their recruiters contacted me) and had pretty much the same experience as him; I won't waste my time with that company again. A bunch of recruiters have tried to get me to interview at Bloomberg LP, but I would never work in that crappy open-plan environment that they're infamous for. But I frequently wonder how much of my success is just from being tall and in-shape, not having any obvious personality quirks, and "fitting in" with the look and the company culture (I interview with more stodgy places, not places with hipsters with arm-sleeve tattoos), rather than due to my technical proficiency.
