In the middle of my 17 years working remotely at a tech megacorp, I moved to a product manager role from a custom engineering manager. A couple of years in to my PM role I was feeling stagnant in my career so I purposefully got a headshot done wearing a sport coat and tie to replace my younger me ponytail headshot on our intranet directory.
The first change I noticed was a major difference in the respect and deference I received on calls. Over the next couple of years, I was promoted twice and was offered several lateral move opportunities.
Obviously, some of this change was due to my intentionality, but I attribute the headshot very highly.
Some important factors: I worked with a large number of salespeople in a highly matrixed salesforce. I worked on large global teams and people from some geos were more obvious in their deference. I am of above average attractiveness.
