About the SQL – Intermediate (VOD Data) Test
Hiring for analytics or database-focused roles often comes down to practical SQL ability, not resume keywords. Canditech’s intermediate SQL section uses a video-on-demand business scenario to evaluate how well candidates write SQL queries, combine data across tables, and summarize results for analysis and reporting.
- Querying data across related tables: Many SQL-heavy roles require people to pull accurate data from several related tables at once. In this table-based scenario, candidates show whether they can connect customer, movie, and rental data correctly and handle records that do not match cleanly. This helps recruiters assess real database querying ability rather than memorized syntax.
- Reporting and metric calculation: Strong SQL users need to turn raw rows into useful business metrics for dashboards, reports, and ad hoc analysis. This area evaluates how well candidates calculate counts, averages, totals, and time-based summaries, then filter grouped results to answer a specific question. It highlights whether they can produce accurate reporting outputs from a relational dataset.
- Business problem solving with SQL: The assessment is built around practical business questions from a video-on-demand rental dataset, not abstract theory. Candidates are asked to identify patterns such as top customers or items with no activity, then return results in a clear, usable order. This gives hiring teams a view of problem solving and day-to-day SQL skill in analyst and developer work.
