100% this. Ageism manifests as dismissiveness or intimidation. Keeping skills current & showing accomplishments negates the first and humility and being personable helps mitigate the second. Sometimes in an interview when I suspect the interviewer is uncomfortable with assessing "their Dad", I throw a lot of curiosity at them about their skills & career & ask their advice about the company or tech stack they use. That helps breakdown the "too old to learn & won't listen to me" stereotypes.
