Their application imposes very inappropriate family socio-economic and marital questions in addition to the customary gender, veteran status, etc., questions. Why do they need to know if my parents were college-educated??

Applied on Indeed. I have direct experience of this role. Applied for it on Indeed. Then was sent to a badly presented National Grid website to fill out additional information and submit my application. Did all of this including submitting my Date of Birth (why?)...took a while to fill out the questions only to be told the job I applied for doesn't actually exist! Such a waste of time and a massive concern about ageism.
