Most Common Power Query Requirements in Interviews are:
Data Transformation Basics => Importing data from different sources (Excel, CSV, databases, web, PDFs) / Cleaning data: removing duplicates, filtering rows, replacing values/ Changing data types properly

Advanced Power Query Skills => M language basics and writing custom functions / Parameterizing queries for dynamic filtering/ Combining data: merging and appending tables with different structures/ Handling errors and missing data (using try...otherwise, Table.HasErrors, etc.) / Grouping data and aggregation in Power Query (Table.Group) / Using List and Record functions for advanced transformations / Working with dates and text transformations / Optimizing query performance with buffering (Table.Buffer) and query folding awareness
