Boston Consulting Group Predictive Analyst interview questions

I attend two rounds. in 1st round, she mostly asked ML basic questions and it was very easy. in the 2nd round (Final), he asked about 1 scenario-based question and I was not able to answer it and he directly ended the call by saying that we can't go further with your candidacy. and I respect his decision.

The process started with an HR interview, then a take-home case study to be done in 48 hours, and finally two technical interviews with data scientist managers focused on machine learning best practices.
