The Reddit post from the supply chain buyer facing an Excel test captures a moment that feels all too familiar. After three years of working with spreadsheets daily, they describe their knowledge as "rudimentary" and admit to basic cleanup work, a handful of VLOOKUPs, and a single pivot table. Our opinion is clear: tests like these measure memorized formulas, not potential. They evaluate how well someone can recall a syntax under pressure, not how effectively they solve problems with data in the real world.
This person isn't failing at their job. They have spent three years navigating exported sheets, cleaning data, and making it work for their planning role. That is real skill. The anxiety here comes from a mismatch between tested knowledge and practical ability. Traditional Excel tests reward the person who can write a nested IF statement from memory but ignore the buyer who knows exactly which columns to clean and how to spot a data export error before it breaks a supply chain. The test is a relic of a time when spreadsheet proficiency meant memorizing functions. That approach is outdated, and it unfairly penalizes people whose strengths lie in understanding data, not in remembering a formula reference manual.
What this means in practical terms is straightforward. If you are preparing for an Excel test next week, focus on the three things that actually matter in a supply chain role: VLOOKUP or XLOOKUP, pivot tables, and basic conditional formatting. Those three tools solve the vast majority of data problems a buyer or planner encounters. Do not waste time on macros, array formulas, or obscure functions. The hiring manager wants to see that you can look up a part number, summarize a purchase order history, and highlight overdue items. That is the test within the test. You can learn those three skills in two focused afternoons.
The deeper issue here is that the industry is still using a measurement tool from two decades ago. AI-native spreadsheet tools already exist that let you ask for a lookup in plain language or generate a pivot table from a simple description. The test is testing a skill set that is being automated. Your potential as a supply chain professional is not determined by how many formulas you can recall. It is determined by how you think about data, how you spot patterns, and how you make decisions under uncertainty. Those are the abilities no test can measure, and they are exactly what you have been building for three years.
