Yes, I have a solid understanding of accounting principles, including financial statements, auditing procedures, and general ledger reconciliation. For VLOOKUP, I explained that it is a function used to look up a value in a column and return a corresponding value from another column. I provided an example: "If I have a table with employee IDs and salaries, I can use =VLOOKUP(Employee_ID, Table, 2, FALSE) to fetch an employee's salary based on their ID." For Pivot Tables, I described how they help summarize and analyze large datasets efficiently. I mentioned a common use case: "If I have a dataset with thousands of transactions, I can use a Pivot Table to quickly group sales by region, filter by product category, and generate summary statistics without modifying the original data."
