Began with a 30-min phone screen with some beginner knowledge questions and light behavioural questions (e.g. a project you enjoyed), then mostly logistics. The actual interview was four 30-min talks with four different people, which were technical, knowledge, behavioural, then your own questions for more of a back and forth dialogue. Really great people, friendly and really willing to help and engage with you. Tech and knowledge was a basic algorithm and then OOD questions about Java.
