I applied online. The process took 3 months. I interviewed at Ogilvy (New York, NY) in Mar 2018
Interview
3 Stages - pretty intense but a great learning process either way.
Apply online, then interview over the phone, then Super Saturday.
Super Saturday is a 2 day event. Dinner in the evening, then full day assessment on Saturday. Mostly behavioral but business acumen and ability to think and ideate on your feet is tested.
Interview questions [1]
