I interviewed at a well-known place here in Portland and they seemed really disappointed that I didn't already know Rails. That was surprising to me, since like the author, I am more familiar with the mindset that you prefer smart people rather than people who know technology X. Beforehand I spent all this time reviewing data structures, algorithms, etc, but they just cared about Rails. I also got one of those goofy OO-design questions about Human inherits from Animal. Not at all what I was expecting.
