I applied through my campus career services office and was shortlisted for an on campus interview. That interview was technical, they asked about tree traversals and similar data structure questions. The next round was a HackerRank, which had more algorithmic questions. Then there was a final phone round which consisted of many rapid fire technical questions which ranged from very quick (UNIX commands) to more in-depth (linked-list traversal techniques). The recruiter was very nice about fitting the entire process into my offer timeline.
