Fractal SQL Interview Question | #fractal #sql #interview #question #dataanlysis #dataanalytics

In this video, I walk through a real SQL interview question asked at Fractal for a Data Analyst / Analytics position. This problem highlights an important reality of analytics interviews — your approach and depth of understanding matter more than writing complex-looking SQL. CREATE TABLE list ( id VARCHAR(10) ); INSERT INTO list (id) VALUES ('F1'), ('F2'), ('F3'), ('F4'), ('F5'), ('M1'), ('M2'), ('M3'), ('M4'), ('M5'), ('S1'), ('S2'), ('S3'), ('S4'), ('S5'); Instead of solving the problem using traditional joins or aggregations, I demonstrate how it can be efficiently solved using a REGEX-based solution in SQL. This approach not only simplifies the logic but also shows how thinking outside the box can give you a strong advantage during interviews. Many candidates limit themselves to conventional methods, but advanced SQL interviews often reward those who understand string manipulation, pattern matching, and creative problem-solving techniques.

If you are preparing for analytics interviews in consulting and product-based companies, mastering techniques like REGEX in SQL can significantly improve your problem-solving confidence.
