The questions that come up for admin, accounts and operations roles, answered the way an interviewer wants to hear them.

1
What is the difference between a relative and an absolute reference?

A relative reference (A1) moves when the formula is copied; an absolute reference ($A$1) stays fixed. Give an example: a tax rate in one cell referenced by a whole column.

2
How do you look up a value from another table?

VLOOKUP with an exact match, or XLOOKUP in recent Excel. Mention the common failure: #N/A from trailing spaces or text-versus-number mismatches.

3
How would you total sales for one region only?

SUMIF with the region column as the criteria range, or a pivot table if several regions are needed at once.

4
What is a pivot table used for?

Summarising a large table by categories (rows and columns) with totals, counts or averages, without writing formulas. It refreshes when the source data changes.

5
How do you remove duplicate records?

Data > Remove Duplicates, selecting the columns that define a duplicate. Before that, copy the sheet so the original is kept.

6
How do you protect a sheet from accidental edits?

Lock the cells that must not change, unlock the input cells, then Review > Protect Sheet. Mention that protection stops accidents, not determined users.

Practise out loud. Say each answer once as written, then again in your own words with your own number or story.

Have a number ready. "My Excel score is at benchmark on a timed test" is a stronger answer than "I am good at it". Take the test and quote the result.
