They had multiple stages, each stage had a simple code/alogorithmic test. I believe there are 3 rounds in total. The first one was very easy, a technical screening interview. The second one is a little more involved- super basic algo/ds and unit test, easy for most developers. Despite solving the problem(s) correctly in the allotted time, unfortunately I did not make it to round 3.

Spent an hour-two discussing with the various members of the team. One member had me build something, and he watched over my shoulder as I did it, to get a sense for how I work. I felt I did strongly here as I was able to share some knowledge of how I did things, and could complete the task in a short amount of time. He also grilled me on an architecture to see how unfamiliar I was with it, but it was new to me so I was actually just unfamiliar. A designer I taught some basics of css, how to use chrome's dev tools to manipulate css properties and experiment. Another member I taught the basics of css positioning. Overall it seemed like a positive experience. I was very surprised and upset to not receive an offer. A common trend among members was css layouts. I get the sense they wanted me to have an answer to their woes, but unfortunately, css is just something you need to learn with time and experience, and I sensed they found this answer unsatisfactory.
