Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time you got stuck on a technical problem. How long did you work on it before asking for help?
What they are checking: Whether they balance independence with asking for help before a delay hurts the team's timeline.
What part of data engineering do you want to get much better at in your first year?
What they are checking: Whether they have a realistic picture of the field and a clear interest in growing in it.
What would you do
A report shows revenue that doesn't match the finance system. How would you start figuring out why?
What they are checking: Whether they troubleshoot methodically by tracing data back through each step instead of guessing.
How would you explain what a data warehouse does to someone in accounting who has never used one?
What they are checking: Whether they can speak plainly to business users, which matters in a consulting firm with non-technical clients.
About the work
Walk me through a data pipeline you've built, even a school or personal project. Where did the data come from and where did it go?
What they are checking: Whether they understand the full path of data from source to a usable table, not just one tool.
Write a SQL query in your head for me: how would you find customers who placed an order last month but not this month?
What they are checking: Practical SQL ability with joins or set logic, which an associate data engineer will use every day.
What's the difference between ETL and ELT, and when would you choose one over the other?
What they are checking: Whether they understand modern data platform patterns beyond memorizing the acronyms.
How do you check data quality in a pipeline, so bad data gets caught before someone uses it?
What they are checking: Whether they build tests and checks in, since wrong numbers in a client report damage trust quickly.
Which cloud tools have you used, such as Azure, Databricks, Snowflake or Python, and how did you learn them?
What they are checking: Whether their skills match common platforms and whether they can learn new ones on their own.
How do you use version control like Git when you work with other people on the same code?
What they are checking: Whether they can work safely in a shared codebase without overwriting other people's changes.
