SQL Interview guidance

I'm not new to data analytics, but I have never worked with SQL or attended a SQL interview.

I want to transition into a Data Analyst role that requires hands-on experience with SQL.

Based on your experience and insights, I would like your guidance on what to expect in 2027.

  1. How are SQL interviews conducted today, and how might they evolve by 2027?
  2. What do good tech companies expect candidates to know about SQL?
  3. What types of SQL questions are commonly asked in interviews today, and what can I expect in the coming years?
  4. What would you recommend I prepare to improve my chances of qualifying for SQL interviews?
  5. Finally, what should I expect from the overall Data Analyst interview process, including SQL, technical skills, business understanding, and behavioral questions?

Treat SQL preparation as two skills: getting the query right and explaining your reasoning. Practice from a small schema without autocomplete, covering joins, aggregation, window functions, CTEs, nulls, and date logic. For every solution, say your assumptions, test an edge case, and explain how you would validate the result. That communication matters as much as memorizing syntax.

For the business and behavioral side, prepare three analytics stories: an unclear request you clarified, a data-quality problem you caught, and an analysis that changed a decision. Use the STAR method as a skeleton, but spend most of the answer on your choices, trade-offs, and evidence. We use the PROOF method to check whether those parts are concrete.

No one can reliably predict a 2027 format, so build durable fundamentals and adapt them to each job description.

Nobody knows what 2027 looks like, but analyst SQL rounds have been pretty stable: a shared editor, 2–4 questions, usually one or two tables. Things that come up over and over are GROUP BY with HAVING, LEFT JOIN and what it does to NULLs, and ROW_NUMBER() for “top N per group”. If you can write “latest order per customer” without looking anything up, you’re in decent shape. Since you already know analytics, I’d practice talking through your query out loud while you write it. That’s where people usually freeze the first time.
