Understand the Role of a Data Analyst

Understanding this syllabus helps you know what topics are most likely to come up in interviews. Many questions focus on Excel functions, data visualization, and how you handle messy or incomplete data.

Brush Up on Excel and SQL Skills
Excel is one of the most important tools for any data analyst. Most companies expect candidates to be good at using formulas, pivot tables, charts, and data cleaning techniques. SQL is another must-know skill, as it’s used to extract and manage data from databases.
