Here’s a theory: Logged hours are used as a gauge to guess your age.
14.000 hrs @ 500hrs/year > 28 years which means you’re probably 50-ish, like your coffee cold and bitter and your application goes to the bin.
5.000-6.000 hrs is early-mid 30’s.
They’re looking for a particular profile and lets face it, age discrimination is easily camouflaged.
