SQL Interview Questions Most Easiest Find The Duplicates Using Max & Min Function

In SQL interviews, a commonly asked question involves finding duplicates using the `MAX()` and `MIN()` functions. The process typically entails grouping data by a specific column, such as names, and using these functions to identify duplicates based on differences in maximum and minimum values. This approach helps candidates demonstrate their understanding of SQL aggregations and conditional filtering, showcasing their ability to pinpoint and manage duplicate entries in a dataset.

Preparing for a SQL interview involves understanding basic concepts, handling joins, and addressing real-time scenarios. Common questions cover topics like queries, joins, and database management. For production support roles, candidates may encounter specific challenges. A comprehensive tutorial, such as the one provided by Haritha Computers and Technology, can be valuable for learning SQL queries. Topics like auto-increment, substring usage, and query optimization are crucial. Aspiring data engineers should focus on mastering SQL fundamentals, ensuring they're well-equipped to navigate diverse interview scenarios.
