re:Work - Guide: Use structured interviewing
Structured interviewing simply means using the same interviewing methods to assess candidates applying for the same job. Research shows that structured interviews can be predictive of candidate performance, even for jobs that are themselves unstructured. Google uses structured interviewing - using the same interview questions, grading candidate responses on the same scale, and making hiring decisions based on consistent, predetermined qualifications.
