BCG X Data Science OA

Hi All. BCG X data science OA came out last week. There was a similar post for the AI Engineer on this page, so im using that post as a template for this . All the info regarding this is outdated (true). The assessment mentions testing the following

• Exploratory Data Analysis

• Data Cleaning and Preprocessing

• Machine Learning and Predictive Modeling

However in the past Ive seen stuff about multiple choice, probability, statistics. Are those still on the assessment.

If anyone has taken the test, kindly reply.

1. What type of questions? What modules are there?
2. How tough is it, and any recommendations to prepare for anything?

Thank you!.
