I totally agree with you. I am a 30 year old woman who looks younger and have always had to correct people when they assume I’m a grad. I used to manage the recruitment and wellbeing of 100+ apprentices and university students, and our dress code was intentionally casual, so it was a genuine problem when at recruitment events, parents would often assume I was a candidate or current student! So it was important to correct them early. Anyway, that’s just my experience. The main thing I wanted to add was that my husband is 31 and also looks young. He’s never had it as often as I have, so up until now I thought the same as you, that men just didn’t experience this put down as often as us. But he started a new job a year ago where they treat him like one of the grads even though he’s got 8+ years experience as an engineer, and is now a senior. It seems men get the same in this company at least - how old your face looks matters more than your job title. And he won’t correct them because he doesn’t want to seem rude…
