Ex-MBB, Experienced Hire; I will teach you not only the how, but also the why of case interviews

# London residents x Avg auto utilisation in a day (%)

Assumptions: First, # of London residents working outside of London = # of non-residents working inside; Second, talking here of cars currently moving (exercise even easier otherwise); Third, traffic constant through the day (otherwise, overweight commute time and severely underweight night time)

Question for you: MBB question, or 2nd tier / boutique? If MBB, above is probably fine and will take you to a roughly right estimation in 2 minutes; if boutique, expect to spend an hour and make 10 thousand calculations to get to precisely wrong answer
