Personal and behavioral questions plus business case. 1 hour in total. The business case was not difficult, since it was a market size. I have been interviewed by two people.

Long, drawn out process (2.5 months). Although Recruiter was communicative, felt strung along and had to check in for updates. Also had interviews rescheduled very last minute. 1) Screener 2) Creative Assignment 3) Interviews with Hiring Managers Was disappointed that one Hiring Manager was completely disengaged / moving around their living room and sprawled on their couch during my final interview. Another creative ego, I suppose. Would have appreciated the same enthusiasm and professionalism that I had as a candidate reciprocated by the interviewer. If they're interested in you, they will expedite your process and make things faster. If they're not interested, they will ghost. If they lost interest, they will string you along and ghost you at their convenience. Was initially very excited about Interbrand, but happy to be moving on to a better opportunity where my time and enthusiasm are actually respected. Treat the process as you interviewing them, not Interbrand interviewing you!
