I interviewed in July at the San Francisco office. I had an initial phone screening with the head of HR, a timed assessment, and an in-person series of interviews.
The phone screening was straightforward and standard, mix of sharing information about the role/org and asking questions.
The assessment was three-part to assess email communication/prioritization, data cleanup/management and calendaring. I received the materials at a scheduled time and had 2 hours to turn it back in.
The last round was in-person and consisted of three interviews with various team members covering specific areas of skills as related to the role.
Overall the interview process was very organized and the team was professional and engaged. At times communication was delayed but nothing out of the norm for applications.
