How to show promotion on resume

The cleanest way to show a promotion on your resume is to list the company once, with your total time there, then stack each job title under it from most recent to oldest, giving each role its own dates and a few result-focused bullet points. That keeps the page from repeating the company name and makes your climb easy to follow. If the two roles were very different, you can list them as separate entries instead; if the move was mostly a title change, keep one entry and add a short line noting when you stepped up.

To make those bullet points strong, it helps to have a record to draw on. Mel Robbins suggests going through your calendar and logging the problems you solve and the value you add 1, and Lorraine K. Lee makes the case for keeping your accomplishments visible rather than leaving them to chance 2. That running record gives you concrete, verifiable results to showcase each time you update your resume for a promotion.
