How to Answer

5. Can you walk us through a data analysis project you completed? What was your process?

This question allows you to showcase your analytical skills and project management abilities.

I started by gathering data from various sources, cleaned and transformed it using Python, and then applied statistical methods to identify key factors contributing to churn. The insights led to actionable recommendations that reduced churn by 15%."
