I didn't take the parent's post the same way. The situation is more that if you do leetcode or hackerrank then you pass the interview. So once again the interview process has failed; instead of identifying good candidates you identify candidates that do hackerrank in their free time.
thanks for the clarification, i read it as "its sad they cant do it, whats wrong with them?" kinda way, but what you said is probably what he/she meant
