There's a phone screening, then a take-home test. That's as far as I got. The take-home test is a mini-project where you are given several CSVs and asked to build a database, ETL, and REST API, complete with unit tests. You are supposed to spend no more than 3-4 hours on this. I wasn't willing to spend that much time on a take-home test, so I requested a pair programming session or alternate technical assessment, but never heard back.
