Initial 30-min. phone call with internal recruiter, then a 1-hour video call with the ECD, then another 1-hour video call with a CD, followed by a 1-hour case study panel presentation, then finally 6 30-min. 1-on-1 video calls.
Almost 7 hours of interviews that dragged out over 2 months, including 2 weeks after the 1-on-1's where I heard nothing from the recruiting team despite sending follow up emails.
