Initially they send a general coding framework assessment that takes ~1hr30min to complete. After passing that, I received an invite to interview with an engineer, who asked me to write two simple functions, and then a more complex third problem with several functions. The concepts are not too difficult but the time limit (1 hr) can definitely be stressful, important to focus on implementing clean, readable, *functioning* code. Finally the last round consists of 1hr of medium/hard algorithms questions, 30min behavioral, and 30min class modeling (object-oriented programming principles). Overall it is a difficult process but everyone is very nice and communicative throughout.
