Personal collection of SQL solutions to interview-style problems from StrataScratch, a data science practice platform with real-world questions used by top tech companies.
This repository documents my SQL problem-solving practice. Each file is named after its StrataScratch problem ID and contains my own solution written in PostgreSQL.
The goal is to build consistency in writing clean, readable SQL and to prepare for data analyst and data science technical interviews.
All solutions are written independently by me. Problem statements and datasets belong to StrataScratch — only my personal solutions are published here.
