The interview process will likely assess your technical skills, analytical thinking, and ability to communicate insights effectively.

Handling missing data is a common challenge in data analysis.
Discuss various strategies for dealing with missing data, such as imputation, deletion, or using algorithms that support missing values.
"I typically assess the extent of missing data and its impact on analysis. For small amounts, I might use imputation methods like mean or median substitution. For larger gaps, I may consider removing those records or using models that can handle missing values."

Provide a specific instance where your analysis led to a significant business decision.
