Ready to crush your Amazon SQL interview? This video preps you for the classic "Find the second-highest salary" question that trips up 80% of candidates.
We break down the optimal solution using a subquery or window function: SELECT DISTINCT salary FROM employees ORDER BY salary DESC LIMIT 1 OFFSET 1—blazing fast for massive datasets. Amazon loves efficiency, so we cover optimizations like avoiding self-joins, handling duplicates with DISTINCT, and scaling for petabyte tables via indexing tips and execution plans.
Perfect for freshers to mid-level devs targeting SDE roles. Practice this + variations (nth highest, department-wise) to stand out. Ace your tech interview?
