FAQ
Is this for freshers with no experience?
Yes. It starts from SQL basics and builds up to window functions, then covers Excel, Power BI, statistics and case rounds in the order most fresher analyst interviews follow.
Which SQL dialect does it use?
Standard SQL that runs as written in SQLite. Notes show the MySQL, PostgreSQL and SQL Server versions wherever date functions or LIMIT/TOP differ.
Do I need Power BI or Excel 365?
No. The Excel workbook works in Excel 2016+ and Google Sheets. The Power BI section explains each measure so you can talk through it even before installing Power BI Desktop.
