🧑‍💼 Interviewer: What's the difference between RANK() and DENSE_RANK() in SQL? 👨‍💻 Me: Here's a quick example using salaries:

SELECT name, department, salary,
       RANK() OVER (ORDER BY salary DESC) AS rank_salary,
       DENSE_RANK() OVER (ORDER BY salary DESC) AS dense_rank_salary
FROM employees;

✔ Key Differences: – RANK(): Skips ranks if there's a tie (e.g., two at #1, next is #3)—great for competitions where gaps show true position. – DENSE_RANK(): No gaps—ranks increase sequentially (e.g., two at #1, next is #2)—ideal for leaderboards or tiers without skips. 📌 Example: If two people tie at 1st place: ⦁ RANK() → 1, 1, 3 ⦁ DENSE_RANK() → 1, 1, 2 💡 Use DENSE_RANK() when you want consistent rank steps, like in sales reports—add PARTITION BY department for per-group ranking! 💬 Tap ❤️ for more! This one's a staple in analytics interviews—practice on sample data to spot the gaps fast! What's your go-to SQL window function? 😊

Data Analytics Interview Questions 1. What is the difference between SQL and MySQL? SQL is a standard language for retrieving and manipulating structured databases. On the contrary, MySQL is a relational database management system, like SQL Server, Oracle or IBM DB2, that is used to manage SQL databases. 2. What is a Cross-Join? Cross join can be defined as a cartesian product of the two tables included in the join. The table after join contains the same number of rows as in the cross-product of the number of rows in the two tables. If a WHERE clause is used in cross join then the query will work like an INNER JOIN. 3. What is a Stored Procedure? A stored procedure is a subroutine available to applications that access a relational database management system (RDBMS). Such procedures are stored in the database data dictionary. The sole disadvantage of stored procedure is that it can be executed nowhere except in the database and occupies more memory in the database server. 4. What is Pattern Matching in SQL? SQL pattern matching provides for pattern search in data if you have no clue as to what that word should be. This kind of SQL query uses wildcards to match a string pattern, rather than writing the exact word. The LIKE operator is used in conjunction with SQL Wildcards to fetch the required information.
