This has been the case for a long time, even with attributes that you have far less control over, such as your height [1]. Given typical social prejudices, I would not be surprised if the height effect was greater for men and the weight effect was greater for women. GLP-1 drugs seem to provide a (relatively) painless way to control the weight effect; the corresponding treatment for control of height [2] is much more…
in an era when interviews are done by zoom, is there a height effect for men?
I did have a weird experience right before the pandemic where the CTO of our company, who had never met me in person before but we'd been on tons of Zoom calls, got visibly upset and even said he'd been tricked, because I was older than he thought. That wasn't a good sign for my future in the slice of the company. The irony here is that he was near retirement age and has since retired. Still, my professional headshot, which was at least a decade old, appears to have set expectations. Guess even on a video call people sometimes see what they expect to see and only during an in-person meeting do they have to confront reality.
