Do you _really_ want to join a company that judges folks based on "got you" style SQL questions? Honestly, that would tell me they don't know how to properly value individuals. Answer from mindvault on reddit.com

r/dataengineering on Reddit: Anyone know of a more advanced version of leetcode sql 50 for prep?
March 6, 2025 -

Hi all,

Wondering if anyone knows of something like leetcode SQL 50 but for more advanced coders that they can share? I have already completed it multiple times and trying to find a source that has very difficult sql questions to prep as I often get tricky ‘got you’ type of sql questions during code screens that are also timed so I need to practice. Please share if you have any ideas thank you.

Leetcode SQL 50 for interview of DA !!!!!!!!
Most interviews focus more on writing clear, business-focused queries, working with messy data, and explaining your logic. You don’t need to complete all 50 LeetCode problems. Doing 10–15 solid ones is enough if you understand the core concepts. Then shift to the StrataScratch platform, which offers more realistic business scenarios. Focus on writing readable queries, using CTEs, and practicing real dataset problems. More on reddit.com

Not able to solve sql 50 questions on leetcode
Not conventional but I’d recommend going straight to the solutions of all 50 problems and understanding them as well as you can. Use an LLM to help explain it if you need. Go back and solve all the problems after a couple weeks. More on reddit.com

Is practicing SQL questions from Leetcode good enough for interviews?
It’s a great start and could get you through but also depends on what you plan to do with SQL for a job. I suggest building out a database from scratch with open data sources, going from an ER diagram to database, to dashboard. Thinking about OLAP vs OLTP. Learn about 3NF, ACID, and etc. The reason is that many jobs may not require this as a necessity but your engineers will appreciate the understanding of it. The complications involved of ingesting dirty data and making it available for others to use gets lost in the background easily. I can’t think of a role that wouldn’t benefit some fundamentals of this outside of DDL/DML statements More on reddit.com

Solving LeetCode SQL-50: Question 1–3 | by Lutfi Andriyanto | Medium
June 13, 2025 - NULL in SQL is not treated as a value, but rather as a marker for an “unknown value”. Because of this, a direct comparison with NULL using operators like =, !=, >, or < will never evaluate to TRUE.
