Initially reached out to HR via the Edelman website after an employee referred me to the position. After the initial call with HR and sending resume/portfolio, I was asked to come in and do three 1:1 interviews with the team that was hiring. Then, I was told they would follow up the next week, but called me within the hour to set up 3 additional 1:1 interviews for the next day. After those, I completed a two-hour writing exam. The third day I completed a phone interview and then two days later was offered the position. Best day of my life!!

Fairly extensive process, you speak with HR, then you speak with at least three if not four or even five people in a series of three-ish interviews. For scheduling, they're pretty quick but you're at the mercy of the interviewers' schedules.
