Drop interview questions on SQL

I was asked questions on joins (like what will be the op if we do left join), window functions. Difference btw union and union all. Order of execution and other basic questions.

I was asked sql questions based on window functions ( rank, cumulative sum etc) , then no.of rows forming on joining two tables in every type of joins.

I interviewed for Angel one, payu, kreditbee, CoinDCX, Zepto. So mentioned an overall type which I have solved.

Focus on Joins, CTEs and Subqueries
