The 5 Pillars of Technical SQL Screenings
Every query in our benchmark suite maps to one of the five foundational competencies evaluated by hiring managers at top tech companies.
Multi-Table Joins & Schema Traversal
Navigating fact-to-dimension relationships, anti-joins with LEFT JOIN ... IS NULL, and self-joins for hierarchical structures without accidental Cartesian fan-outs.
Aggregations & Conditional Logic
Complex grouping, HAVING filters on aggregate thresholds, and conditional pivoting using SUM(CASE WHEN ...) across multi-million row tables.
Date-Time Arithmetic & Cohort Curves
Truncating timestamps with DATE_TRUNC, interval deltas, first-purchase cohort grouping, and Month-over-Month growth calculations.
Advanced Window Functions & Ranking
Differentiating ROW_NUMBER vs DENSE_RANK on ties, running totals, lead/lag event comparisons, and quantile bucketing with NTILE.
Data Cleaning & NULL Edge Cases
Safely handling three-valued logic, COALESCE defaults, string manipulation, deduplication with partition ranking, and zero-division guards.
