Applied through their website. Had a first phone screening with the HR person about generic topics (motivation, my work history, etc.). Had a second phone call with a tech lead about mildly technical topics. He then gave me a home assignment. The assignment was, in my opinion, unreasonably time-consuming, especially due to the number of requirements and constraints. Given the mixed reviews on Glassdoor I thought it was probably not worth it and took myself out of consideration.

Requires new hires to take a somewhat taxing take home assignment. They estimate it at 20 hours, and you get a week to complete it. It is well put together, and gets around showing you what the company is about. The interview themselves were a very nice experience, and it is clear that management in engineering cares about what kind of people they let in.
