Difficult interview

Application

I applied online. I interviewed at Boston Consulting Group (Boston, MA)

Interview

It’s pretty straightforward overall, but there’s also an intermediate Python test where you’ll need to handle real-world data cleaning tasks independently, without external help, so be ready to troubleshoot messy inputs, missing values, and edge cases.

Interview questions [1]

Question 1

Clean the dataset by parsing the date column to datetime, removing rows with missing or invalid amounts, and dropping duplicate records based on user_id and timestamp.
