Began with a phone screening, then scheduled a skills assessment, which involved a speed section (basic math and logic questions but with a tight time limit), a section where you learn a made-up programming language, and four typical programming questions.

If you do well on that, they bring you out to their campus. At that point, the only interview parts are a case study where they ask you to think of a solution to a relevant challenge they have faced and explain your thoughts, and a section where you have to explain a past project to a developer. It's overall pretty informal and I actually had a lot of fun on my visit.

Talk about one of your past projects.
