This was one of the reasons why I applied. I wasn't entirely sure it was the right fit (my current job is flexible, which is good, vs a grind, and I'm happy there) but I wanted to study their ways a bit and see what I could bring back, because my company has made some remarkably terrible hires over the past few years.

In short, it's a very well designed "build an app" take home test. There isn't a solution so to speak, but its designed to test your product-engineer aptitude as well as your execution speed, as there are things to get done and requires some thoughtfulness. One can go in a lot of different directions with it. Code can look great, but did you build the right thing, something actually relevant? That's what's important.

Its the sort of test that would instantly filter out 99% of applicants, because of the product emphasis vs the code emphasis, and good product engineers are rare. One could be the best coder around but not have a clue what to build. They want people who know what to build.

I had a lot of fun working on it and loved the challenge, but ultimately didn't know what to build and was fishing a bit, being more of a platform engineer vs product engineer.
