Intense.
Phone call with a recruiter to start, then you'll meet with the hiring manager and complete an editing assessment. Final round is two or three back-to-back interviews with multiple members of the team and higher ups of the department. Each interview is filled with very thoughtful questions, it can be a bit exhausting. Can't help but be disappointed that after such an extensive process I didn't get an offer, but it makes for good interview practice. Thankfully everyone is incredibly nice.
Long story short: expect lots of questions and prepare specific answers
