I organized a team meeting to brainstorm solutions, and we decided to implement a data cleaning process that involved cross-referencing with external datasets. This not only resolved the issue but also improved our data accuracy.”

2. How do you prioritize your tasks when working on multiple projects?

This question assesses your time management and organizational skills.

How to Answer
