Data Architect Interview Questions
Data Architects design, deploy and maintain systems to ensure company information is gathered effectively and stored securely. They analyze both user and database system requirements, create data models and provide functional solutions.
Your ideal candidates should have solid technical backgrounds, acquired by Data Science or relevant IT degrees. Use the following interview questions to test candidates on their knowledge of key database structure principles and statistical analysis tools. Include a written assignment in your hiring process to better assess candidates’ skills in SQL and programming languages that you use.
Interviews are a good way to evaluate soft skills, as well. Data architects are problem solvers who can proactively address malfunctions. They usually work with Data Analysts, so it’s best to focus on candidates with collaboration skills who perform well in team environments.
