You think not knowing about Bloom Filters is a 'humorous gap in knowledge'? Are you saying you worked some place that expected people to know about them and also hired self-taught engineers? I've worked at some companies people here think of as 'elite' and I can't even begin to imagine how this might occur. In fact, it smells to me a lot like the mentality of certain people at said companies who liked hazing interviewees by testing esoteric knowledge (e.g. twisted DP problems, reservoir sampling) instead of talent and potential. A part of me would have loved to see those companies implement a policy of using those interview questions on other employees, like a kind of 'random drug testing'. I imagine many would have been humbled rather quickly by such a process.
