  • How do i practice SQL to be real world ready?
    There was a comment here about using Leetcode, Hackerrank, SQL fiddle, etc to keep learning SQL.

You should grind on some data analytics/data science focused platforms like stratascratch and interviewquery. They have hundreds of questions with many free ones for your to practice.
