do you do this outside of work hours? sounds more like a failure on how the company operates than the nature of the problem. taking a wild guess that if it weren't for combing through through applications, then those extra hours spent on mindless HR stuff would simply be filled with other work.
It doesn’t matter when you waste someone’s time; work hours are fungible for most professionals. Your ‘wild guess’ seems very convenient with respect to your previous comment, and happens to be incorrect.
