Process
I submitted my resume and cover letter to the job board. A couple of weeks later, I was sent a link to a HackerRank challenge.
I completed the challenge and passed all the test cases. I did not get the spot, but whatever. I did apply rather late.

Pros: Working at Duolingo has been nothing short of amazing. I've had an opinion on everything that I've worked on since I've started. I work on a really great team of developers, designers, and PMs, and working so closely every day, we've formed some great bonds. Many of my coworkers I consider close friends.
The open office makes it easy to get to know everyone and become familiar with almost everyone you're working with.
Cons: I can't think of any downsides to working at Duolingo.
