About This Session
A focused 2-hour live session on SQL — the most tested skill in data roles, backend interviews, and analyst positions alike.
We moved through SELECT fundamentals fast and spent the majority of the session on real complexity: multi-table JOINs, correlated subqueries, CTEs, and window functions like RANK, DENSE_RANK, and LAG. We also covered query optimisation fundamentals — when indexes help, when they hurt, and how to read an EXPLAIN output.
This session is now closed. Join the waitlist for the next SQL workshop.
What We'll Cover
- 01SELECT, WHERE, GROUP BY, HAVING — the ones interviews actually test
- 02INNER, LEFT, RIGHT, FULL JOINs with real scenarios
- 03Subqueries and correlated subqueries
- 04CTEs (WITH clause) — writing readable complex queries
- 05Window Functions — ROW_NUMBER, RANK, DENSE_RANK, LAG, LEAD
- 06Indexing fundamentals and reading EXPLAIN plans
- 0710 real SQL interview questions solved live
What You'll Walk Away With
- Write complex SQL queries without hesitation
- Use window functions for analytical problems
- Optimise slow queries with proper indexing
- Crack SQL rounds in data and backend interviews
