How to Assess Candidates on Data Hygiene

Assessing candidates on data hygiene is crucial for finding individuals who can maintain clean and accurate data. Here are a couple of effective ways to evaluate their skills:

This hands-on approach helps you see how well they can identify and fix problems in real-time.

2. Situational Judgment Test: Another method is a situational judgment test, where candidates are presented with scenarios related to data hygiene challenges. They need to explain how they would respond to ensure data accuracy and cleanliness. This helps assess their problem-solving abilities and understanding of best practices.
