Ep58 - 75 SQL Problems!! Most people don’t fail data analyst interviews because they don’t know SQL They fail because they don’t practice the right type of questions. I’ve seen many candidates spend weeks learning SQL concepts — but when real interview questions are asked, they struggle with how to apply the logic. That’s why this list of compiled 75 real world SQL problems will help you to prepare for any data related roles. These questions will help you understand: • how interview questions are framed • how to approach joins, aggregations, case statements logically • how to improve problem solving speed • how to gain confidence before interviews Follow @fitwit_krish and comment SQL. I’ll send the complete list. Save this reel so you can start practicing before your next interview.

save this + follow for part 3 to see the step-by-step of how to fix each of these in SQL 😉 Comment “data” for my free 5-day data career kickstart course to learn the basics of data careers, SQL, and portfolio building 🥰 Your data can look clean on the surface and still be a disaster underneath.💀 In part 1, I used @claudeai Code to build a dirty dataset AND a full answer key from scratch. Let’s explore that dataset and see what needs to be cleaned. Here’s what we found from the first look: ↳ duplicate order IDs hiding that would cause you to overcount in every aggregation ↳ inconsistent category values such as “Books” uppercase, lowercase, and spelled wrong, all being treated as separate categories ↳ columns that looked clean but were actually full of empty strings instead of nulls, meaning a basic null check would miss them entirely The last one is the sneaky one: Somewhere upstream in the ETL pipeline, nulls got coded as empty strings. You HAVE to know to look for it. Exploring dirty data before you touch it is the step most people skip. You can’t clean what you haven’t looked at 💀
