At least in the US, a person's job is a big part of both their identity and their brand. "What do you do" is one of the first questions that come up in most conversations, and everyone judges everyone else (at least subconsciously) based on the response.

Back in another life I did a lot of online dating and tested this hypothesis by telling some of my dates that I worked as a garbage collector for the city. Those dates pretty much always ended early. :) I had drastically higher success when I told them my real job: software consulting.
