Applied through my university. My first interview was just a half hour chat with an Engineer from the networks team. It went pretty well. No technical questions were asked. Although I heard that some panels asked candidates to write code. The super day at their New York office had 3 back to back interviews. Two of which core-technical and one behavioral with a Team director. The technical interviews spanned across algorithms, basic computer science, networks, operating systems and even some finance questions(because I had a finance background)

Participated in their one day event so got fast tracked to the final round. One 30 min interview with two interviewers. Easy leetcode questions, followed by a few behavioral questions
