There are several stages in the interview process: (1) A long written interview (25-35 long answer questions). Be prepared to write 10+ pages in response. (2) An aptitude test. (3) An long take-home technical test. Probably 6+ hours of work. (4) "Early stage" interviews with a variety of employees, including your hiring lead. (5) Meeting with a member of the "Talent Team" (not sure about this, I didn't make it this far). (6) "Late stage" interviews.

Terrible, extremely inconsiderate of candidates' time. Included 3 interviews, IQ type test, extended questionnaire before getting declined with potentially more steps if I had continued. I would not recommend wasting your time.
