I received a phone call on the information, then a technical challenge was given to me with about a 2 week timeframe spent working on the coding challenge that they gave me. Afterwards I had an on-site interview.

Write two essays, if selected, take home a coding challenge - a game, then go on site for 4-5 hours for 4 interviews: 2 informal, then 1 with a hiring manager, and one with 2 engineers where you discuss the code you wrote.
