About This Course

The SQL interview round is the #1 filter in Data Engineering hiring — and most candidates fail it. This isn't another SQL tutorial. Every lesson, every practice problem, and every premium challenge in this course was reverse-engineered from actual Data Engineering interview rounds at Meta, Amazon, Google, Microsoft, Apple, Netflix, and 6 more top-tier companies. What makes this different: You won't just learn SQL — you'll solve the exact same problem patterns that interviewers use to separate senior-level candidates from the rest. 10 chapters. 85+ hands-on exercises. 30+ real FAANG interview problems. Zero fluff. Built by a Sr. Data Engineer who cracked DE interviews at Meta, Amazon, and Samsara with 500+ real interviews under his belt.

What You'll Learn

✓Solve 85+ SQL Problems Under Pressure: Practice in a real interview-style IDE with time constraints, company-tagged problems, and hidden test cases — exactly like the real thing.

✓Master Every JOIN Type Interviewers Test: From INNER and LEFT to Self Joins, Exclusion Joins, and Multi-Table Chains — the JOIN module alone covers 8 types with 24 hands-on exercises.

✓Crack Window Function Rounds — The #1 Senior DE Filter: ROW_NUMBER, RANK, DENSE_RANK, LAG, LEAD, NTILE, FIRST_VALUE, Window Framing — 32 exercises covering every pattern Amazon, Meta, and Atlassian throw at candidates.

✓Write Production-Grade GROUP BY & Aggregation Queries: Go beyond COUNT(*) — learn GROUPING SETS, ROLLUP, CUBE, and HAVING for the multi-dimensional analytics questions that separate mid from senior.

✓Think Like an Interviewer: Every module ends with a real premium problem sourced from actual FAANG DE rounds. Understand not just WHAT to write but WHY interviewers ask it.

✓Build a SQL Foundation That Never Cracks: DDL, DML, Key Constraints, Data Warehousing concepts, CASE expressions, NULL handling, Date functions — the fundamentals that 80% of candidates get wrong under pressure.
