NCed for this one. I feel that there's a subconscious, maybe even conscious bias against employing women over 4O. Especially if they're still more junior in a professional role due to a career change etc. We're now really good at spotting sexism (for younger women), racism etc, although much further to go. But ageism is hardly ever mentioned.
It's particularly bad in my industry (tech) where it's young - mostly staff in their 20s and 30s.
Find it quite depressing when we might need to work another 30 years after 40.
