Looking for a past article - lost and found

Few months ago I read a article on HN front page about a guy's blog post in which he had shared is journey about finding out he had two weeks to find a place and a job in silicon valley. He described how he used each interview as a stepping stone and dealt with the typical puzzles questions;and then as he gave more interviews he started asking some of those puzzles he had encoutered in other interviews back to his interviewers to 1)see how smart they were and 2) make a strong impression. If anybody else read this article and has it bookmarked can you please share the URL . Thanks.
