This smells more like desperation than passion.
> It also requires intelligence.
I agree, but intelligence is a very wide term and I'm not sure that the "intelligence" that you need to find patterns and memorize a few numbers is the same "intelligence" you need to make good programs. I guess it is positively correlated, anyway.
They are one and the same. If you're a nice company a lot of people want to work for, those who want to are prepared to go through hurdles in order to do so.
> I guess it is positively correlated, anyway.
Memory is very strongly correlated with IQ.
No, some people are interested out of desperation, others have established themselves in the industry and _will not_ go through your hurdles because they can afford not to.
Imagine getting 100 recent graduates because they got no other offers while people currently employed elsewhere scoff at your hurdles, imagine the team you're going to be building.
I mean if they know ahead of time that you are going to ask them to regurgitate these numbers, then they are just going to memorize them right before the interview. What does that really prove? Certainly doesn't prove passion IMO.
