I don't know if these tips help that much. My dad is an older electrical engineer, with experience with embedded systems, telecommunications networks, Unix, and R, Python, and Data Science. He regularly has great phone interviews only to hear after the in person interview "We are moving forward with a different candidate." My dad however is nearly bald with grey hair and his skin is a little worse for the wear. I am very sad to seem him like this and wish I could do something for him. The only thing I can think of though is to tell him to look for remote roles so that they don't see what he actually looks like and won't discriminate against him.
