The problem is they bill themselves as a staff software engineer. Such a glaring visual issue makes me question their core competency, which makes me question any advice they could offer. Of course they might still be amazing at professional coaching, but maybe don't bill yourself as a former engineer if the first visual impression is very clunky engineering.
But mainly it is a ad to hire her as your coach.
