The process consisted of a quick phone call discussing my resume and the current Java positions. Then a very medium difficulty home coding challenge to ingest event and calculate statistics on it. Then they invited me for the final onsite interview. It was 2.5 hour tech interview and lunch afterward. The tech interviews were of average difficulty and involved some general Java and database questions. Although, there was a python guy who asked some weird question about python and bash even though I've applied for Java position. All the interviewers were very nice and I could tell they are bright people.
