Now Mollie sometimes gets special outfits for special days, much like the Google doodle. For May 4th, for example, Mollie got light sabers: https://slate.com/technology/2018/05/u-s-digital-service-deb...
It might sound silly, but we actually got an application from that Slate article. A little whimsy can go a long way in government. We have a lot of crab-themed decorations around the USDS townhouse in DC. I even have a crab drawing my nephew made hanging right next to my desk.
One more observation: If I were to want to work for the USDS, there aren't job listings (that I saw) nor would I know what I was applying for by clicking the "Apply Now" button.
I have been out of Fed. Gov. for about a decade, but the hiring process was very complex and confusing back then, the "rule of thumb" was for people to apply to as many as thirty jobs, and expect to wait a month for a response. I'd recommend explaining how (if) USDS is different. I certainly wouldn't fill out the "Apply Now" form not knowing what I'd be interviewed for, in DC, with a response sometime in the next month.
The bottom line is that we are always looking for strong designers, engineers, and product managers and we can hire them quickly (in government terms).
Glad you noticed the easter egg in the source code! You know that means you have to apply now. :)
