Most people use SQL daily… but interviews test how deeply you truly understand it. 👀 If you’re preparing for Data Analyst/Data Engineer roles, don’t just memorize queries — understand the logic behind joins, subqueries, aggregations, and filtering. In this video, I break down what interviewers actually look for and how you can prepare smartly. 💡 🔖 Save this for your SQL prep 💬 Follow for more free analytics resources #SQL #SQLInterview #DataAnalyst #DataEngineer #learnsql

The SQL you write tells interviewers exactly what level you're at 💼⁠ ⁠ Most people write subqueries because that's what tutorials teach. Here's why senior analysts write CTEs instead:⁠ ⁠ Subqueries force you to read inside out (confusing, error prone, hard to maintain). CTEs define logic sequentially (calculate totals, then average, then filter). CTE version explains itself (your future self and teammates will thank you). Subqueries repeat logic (one change breaks everything). CTEs are modular (update one step without touching the rest).⁠ ⁠ If you hand subquery code to a senior analyst in an interview, they already know your level. CTEs signal you think like an engineer, not just a coder.⁠ ⁠ Comment "CODE" for the full script and save this before your next SQL interview 📊⁠ ⁠ #SQLInterview #AdvancedSQL #CTEvsSubquery #DataAnalystTips
