I applied online. The process took two months.

• 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.

The in-person technical interview problem involved clever usage of hashmaps and hashsets.
