1 hr phone screen with 3 engineers, followed by a 2 hr in-person interview with 2 engineers, a manager, and a director. They asked a lot of Java-related questions, 1 situational question, then had me present my favorite project I worked on. The director then presented their system architecture.

Questions about design patterns I've used, the difference between TCP and UDP, how to communicate between a producer and a consumer thread, how to instantiate threads, and how to do a Singleton pattern. How to handle a difficult situation with a co-worker.
