So, You Have To Wear Makeup - Postscript

Because a couple of people have asked, here are the numbers for the responses I got to my anecdata collection. The question I asked was, "Have you ever been to a successful job interview without makeup on? If so, which industry?"

Out of 35 respondents (give or take, I might have missed a few on Twitter), 4 answered No. They had never been to a successful job interview without makeup, and they all clarified that they had never been to a job interview without any makeup full stop. The industries these women worked in were engineering, advertising, law, and cosmetic retail.

31 answered Yes, they had been to successful job interviews without makeup. Before my statistician friends jump in, I'm aware the way I asked the question created an enormous bias. I factored that into my conclusions :P
The industries these women worked in were surprisingly varied. Here's a brief list, where I've listed (multiple) next to any industry that had more than 2 respondents;
