Four rounds of technical interviews, including team members, managers, directors, and senior fellows. Interview times are around 30 minutes. The interview lasted about 2 weeks, and waiting for the offer for one month.

2 - hour phone interviews broken up into four 30 min segments, 3 of them with managers, and last one with HR rep. Mostly questions about my research experience. Received offer but did not accept due to better offers at other companies.
