Brief phone interview to ask a few questions about your resume, followed by a long at-home coding test.

Someone (a third party) watches you complete a test which involves a coding and math test. The math portion tests quick calculations of common things, none of which are above algebra. The coding questions took me a while, but were nothing super tricky or unheard of.

After the test, I heard back fairly quickly for an onsite interview. The most important parts were a technical project discussion interview and a behavioral (tell me about yourself, what you want to do) interview.
