Hi,
I've been invited to round 1 interview at Bain London, which will be comprised of 3 interviews of 35-45 min each (1 behavioural, 1 case and 1 market sizing/estimation).
If the market sizing/estimation case is expected to take the entire 35-45 min, then how complex a question should I expect?! Most market sizing/estimation problems I expect take around 15 min max (structuring and calculation), so I'm a bit confused about how it will take up the entire length of the interview.
