Round 1: One-way Interview
Watched pre-rerecorded video of someone asking a question (I think there were 5 total?) and then you time to record your answer
Round 2: Phone interview with someone from HR
Round 3: 3 hour Zoom interviews broken up in 30 min segments with 2-3 people each round. (the people you'd be working with)
Overall, it was a very nice experience and not very stressful. Everyone was very nice and informative!
