I know boards that don't take 1-2 days to hire the CEO. If you need that long, you are either asking the wrong questions or you have the wrong people hiring (the chances of the latter occurring in tech, where business skills are generally lacking, is high).
But yeah...people in tech seem to believe all kinds of weird stuff about hiring...if you are asking someone to come in for 2 days for a non-executive position, you are lighting bags of cash on fire.
