The interviewer called while I was working on a Google Doc. Initially, I was stuck. During the conversation, he provided helpful hints, and at the end, I was allowed to ask any questions.

One or two rounds of virtual interviewing including behavioral, research discussion, and technical interview. Then was flown out to one of their campuses for two in-person interviews including a technical interview and a research discussion. I was rejected after this phase but the next steps would have included meetings with team leaders for team placement.
