are you working on an open project that involves team? Then IMHO you need comments, but most of the time I develop website and app by myself and I don't need much comment for explaining, only as reference as to what the code section is, and no one has complained about it yet

Agree with ricardobeat, but if I am a manager myself, I imagine I would ask for a question like have you ever made any software? Open-source or commercial. Or any experience in developing any open software.

twitter and facebook is already popular social network, many have gotten used to it, I ask why my friends didn't use google+, they say they are already lazy to set up another social account if they have one or two already...
