🚨 THESE are the SQL questions that separate the juniors from the seniors. 🚨 ​You can study syntax all day, but when an interviewer drops question #17 on you, can you code it under pressure? ​Don’t be the 90% who freeze. This list is your blueprint. ​I've compiled the most frequent, job-critical SQL queries from dozens of actual FAANG and top tech interviews. Master this list, and you aren’t just ready for the interview—you’re ready for the job. ​👇 YOUR CHALLENGE: 👇 ​Drop your solution to Question #15 (Calculating the running total) in the comments below. Let's build a massive resource together. Let's see who can write the cleanest, most efficient query! ​Share this with someone who needs this for job. 🚀 ​[SQL interview questions, data science interview, data analyst technical questions, FAANG SQL, advanced SQL queries, window functions SQL, joins vs CTEs, relational database, database normalization, query optimization, data engineering prep, coding challenge, tech interview, tech skills, structured query language, database fundamentals, data professional, career in data, interview prep, problem-solving SQL] ​#SQL #InterviewPrep #DataScience DataAnalytics DataEngineering

You DO NOT need to learn everything to become a Data Engineer. People often prepare for mid-level roles while applying for entry-level roles. Here’s what actually mattered for me in the beginning when switching from testing to a data engineer role. 1. SQL(non-negotiable): You’ll need to know the basics and complexities of sql along including subqueries and window functions. If you’re not strong in SQL, you won’t be able to move forward in interviews. 2. Python concepts basics like lists, dictionaries, sets and basic problem solving. You can solve questions in other languages too but I’d suggest Python as it’s easy to learn. You don’t need hardcore DSA for most entry-level Data Engineering roles, but DSA is definitely important. 3. Data warehousing concepts like facts vs dimension, star vs snowflake schema, SCD Type 1,2 etc. Understanding concepts and what data warehousing is and why it’s there mattered more than tools. 4. ETL and data pipeline understanding. How data is extracted, transformed, loaded is the CORE of Data Engineering. You don’t need spark understanding in the beginning, just the understanding of how data flows in and out. 5. System design basics, not like design twitter/uber. Simple understanding of how data moves end to end and overall understanding of data eco-systems. No deep design is expected at entry-level. 6. Pick any one cloud. Don’t chase all clouds, just any one cloud and cover its basics because you’d most likely be working on some cloud in your work. I moved from Testing to Data Engineering by focusing on these basics, instead of trying to learn every other tool out there, and it is still the very core of Data Engineering which one must know to crack interviews. Save this if you’re planning to make a switch into Data Engineering. . . . . .
