First off the questions with age implicit implications are 100% illegal in the US full stop. Second it sounds like the companies you applying for are sh*tshows (based on those interview questions) and you may have dodged a bullet there. The funny thing about ageism is its the one form of discrimination that affects every single person and yet its the one that I have not seen a single tech company take a stand against.
