I interviewed at Boston Consulting Group (New York, NY)
Interview
First a online One-way interview, then online python coding round, then is a live coding+technical case with real person, last round will be 3 technical cases with partners. Case can be technically challenging
One technical round with basic python/EDA/ML questions, followed by a case round, followed by 3 back to back cases. The cases were testing fundamentals, and how you respond under pressure, as well as your communication and applied data science skills
Interview questions [1]
Question 1
1. Predictive maintenance case - if you have more time how will you explain to a client how you'll improve a model
2. Random forest - if you have a noisy dataset (lots of features that don't matter) whats the probability of the 2 features of interest being present in any single tree that randomly selects 50 features out of 100
I applied through other source. The process took 3 weeks. I interviewed at Boston Consulting Group in Feb 2026
