A lot of the interview questions I got are some of the most common interview questions that are being asked recently, so you don't really need to prepare that hard assuming you've done other interviews recently. The technical questions are about Elixir basics, so I suggest brushing up on the intro documentation for Elixir and Phoenix before getting into the technical interviews. The take home exam is about building a REST API using Elixir and Phoenix. The exam itself is pretty simple, but they're requiring you to modify the seed file to create thousands of records which suggests that they want you to think about scaling throughout the exam.
