1) I like to ask questions during interviews. I hate the whole "I'm a brilliant guy charade." I'm not. You're not. Einstein was. Deal with it.
2) And I especially don't have a care for rote memorization bullshit for things I can look up in less time than it would take me to remember. I'm a thinker, not a fucking textbook.
So, if you said to me "do whatever using x algorithm", and I said to you, "I don't know x algorithm by heart; could you tell me what it is, and I'll implement it in one of the languages I'm proficient in?" would that just completely turn you off to me as a candidate?
