Hello folks,

If you’re preparing for a tech interview, there’s one skill you absolutely cannot afford to overlook: SQL.

Whether you're aiming for a role in data engineering, software development, data analysis, or even product management, SQL is a must-know for cracking technical interviews. It’s the backbone of data manipulation, and interviewers love to test your ability to write efficient, clean, and accurate queries.

If you have gone through tech interviews, there is a good chance that you have seen queries like "How to find second highest salary of employee" or "Nth highest salary", or "How to remove duplicate rows from a table?"

Apart from queries, there are also questions like how do you design a database for a given scenario like how to design a Timeseries database in Oracle or any other relational database, what are you supposed to remember when creating index? How SQL optimizer work? How will you fix a slow query problem and so on.

Many developer prepare well for Java, Spring Boot and other programming language but fail to give enough attention to SQL which often cost them the opportunity.
