Who this is for:

For students, freshers and anyone prepping for a data analyst, data engineer, or SQL-heavy interview who wants a structured plan instead of randomly solving problems with no direction, or endlessly searching for the next tutorial instead of actually practicing.

Day 5 is the one that matters most. Window Functions are the single most-tested advanced SQL topic in interviews, and this guide gives it the attention it deserves.

Print it, fill it out, tick every box, and walk into your next interview like you've already done this before.
