Employers need analysts who can independently verify the accuracy of numbers produced by others, a documented responsibility for analyst roles in Philippine financial services.
List two or three error types: hard-coded inputs in formula ranges, broken or inconsistent links, and totals that do not tie to line items. Then explain the Excel feature or manual check you would use for each.
Start by naming the three most common error types and then immediately attach a detection method to each. For hard-coded inputs buried inside formula ranges, say you use the Go To Special function to select constants, then scan the selected cells against the assumptions tab to confirm every input is sourced from a cell reference. For broken or inconsistent links, mention that you press Ctrl plus the tilde key to display all formulas on the sheet, which lets you spot references pointing to the wrong sheet or to a stale file path, and you also use the Edit Links tool to check for external workbook dependencies that may have gone missing. For totals that do not tie to line items, explain that you rebuild the sum with a quick manual addition or use the SUM function on the visible range, then compare it to the reported total to catch rows hidden by filters or accidentally excluded ranges. Close by saying you always trace precedents on the key output cells to verify the chain of calculations flows from the assumptions page, and you do this in a calm, systematic pass rather than relying on memory.
A common mistake is to say, 'Tiningnan ko lang po kung tama yung total' without naming a method. Instead, walk through specific techniques like trace precedents, check sums, or comparing formulas to the assumptions page.
Situation
In a final-year financial analysis course, I reviewed a teammate's revenue projection model before our group presentation.
Task
I had to confirm that the model's assumptions, links, and totals were correct so the grade would not be affected by avoidable spreadsheet mistakes.
Action
I started by separating input cells from formula cells and looked for hard-coded numbers sitting inside calculation areas. I checked every cross-sheet link by using trace precedents, then compared the model's implied growth percentages with the original assumptions page. I also inserted a simple row of check sums that summed the individual line items and compared them to the reported totals in the summary tab.
Result
I found one sign error in a cost line and a broken link to the tax rate cell, both corrected before the presentation, and the group received a high mark.
Always test a model against its own source assumptions, not just against itself.
