Q: num_list[1,2,3,4,5] are red numbers, api to return first non-red number in a list (at least I think so... because the interviewer himself seemed rather confused about his own question and kept amending and changing the various details pertaining to what he wanted adding only later that this was a sorted list and then changing other aspects such as no negative integers as I attempted to code what I thought he wanted). I presented a working solution at which point we got the (highly relevant to our daily work and totally stupid) big "O" complexity question that I also answered. And then he proceeded to indicate that he did not even understand how Python does not actually have "integer overflow" ... anyway...
