AppDynamics brings you onsite to interview. The process starts at around 10:30am and ended at 4:45pm, for me. There are not a whole lot of breaks so be prepared to talk to a lot of people in one sitting! The interviews are not terribly difficult, but challenging enough to keep you on your toes. Chances are that you will be exhausted at the end of the interview, since you talk to 6 different team members, and your recruiters check in with you 2-3 times throughout the day.
