I had a front-end long-term contract many years ago that required expertise with C#, WPF, Silverlight and something else I forget. I had those things covered, but I soon learned that I was also supposedly an expert in SharePoint and an experienced graphic artist. The reality is that if they had given me any requirements for SharePoint I could have built that for them even though I had never used it. But graphic design I had no interest in. A few weeks in there was a lunch with recruiters and contractors for the project and one of the other recruiters (not the one who submitted me for the job) asked me something like, "when did you first realize that you loved to draw?" or something. I told her honestly I was horrible at drawing and not interested in it.

One of the reasons I got fired from that contract eventually (aside from a fight with a manipulative SOB who was fresh off a career as a local TV news personality and was holding the project up in his backend role) was that they were disappointed with my lack of interesting user interface designs.

I never told anyone I was a graphic artist. Even if I did have that skill (or interest) (which I had neither), I was too busy dealing with new WPF/XAML/C# features and software design etc.
