As a developer, I've served for nearly 2 decades, always javascripting. IMO, all 4 challenges above test the modular arithmetic knowledge of a candidate. Being a direct individual, I would simply ask a candidate if they know what mod does.
I have been belittled by self proclaimed GURU's who know a few tricks (tricks are for kids!) in the interview process so many times that I've felt like the most useless developer who's ever been or will be.
In general, I'd say testing someones coding during an interview process shows how incompetent the interviewer is! Just don't do it!

We're a place where coders share, stay up-to-date and grow their careers.
