alt Hacker NewsInterviewing is a skill. I think that he got really good at it, both in tailor his CV as well as the process itself. It probably worked on the process and make adjustments. Based on the what I’ve read, it seems that he was interviewing all the time.
So, IMHO, he focused in the interview process over everything else, including understanding and exploiting the blind spots. He iterated and refined it, until, he became a master of it.
He really seemed to be not great at the work itself, though. He was being fired after a couple of days, which I don’t think is common. You really have to do it very badly to be fired so quick after being hired.
This is what happens at top consulting firms. Top 5% interview skills, especially as smoothing your way through a case study. But when they actually come consult for your business, it’s just not what you pay for given what you’ve been led to believe with those case studies.
