I interviewed at Boston Consulting Group (New York, NY)
Interview
First round was recruiter screening that I gave months ago. second was the OA, which was a mixture of stats, ML theory MCQs, and then a bunch of Data Science Questions which were to be given in a jupyter notebook. The data science questions were built on top of one another, but were very typing-heavy and lengthy, so would suggest practicing pandas and scikit learn in advance.

Coding challenge, then soft skills which i did not get to. Coding challenge was online timed in a third party tool. Not very hard but needed more time and didnt move quick enough.
The process includes six stages: HR screening, CodeSignal online assessment, basic pandas and data science case interview, followed by three business case interviews focused on practical problem-solving and business impact.
