I applied through university. The process took 4 weeks. I interviewed at Oliver Wyman in Nov 2024
Interview
Three rounds
Round 1: basic ml resume and case studies related to ml (how to get features, pre processing, training,testing)
Round 2: pure case study (would advise do iim case books for each type of case and structure) and in some cases can expect guesstimates
Round 3: mostly HR oriented
Interview questions [1]
Question 1
Assumption of logistics regression
Random forest random tree etc
Multiple rounds covering Data Science and business case studies. Interesting choice of questions and good puzzles. For preparation, I would suggest brushing up on ML fundamentals and practising case students from casebooks of business schools like IIMA, IIMB and IIMC.
I applied through a recruiter. The process took 3 weeks. I interviewed at Oliver Wyman (London, England) in Sept 2017
Interview
The person I discussed with was very friendly. He explained to me what would be my role, how they work there, and what they were looking for. Given it was a first interview, I haven't been challenged from a technical point of view.
