Getting promoted, even once, tells a hiring manager something no skills list can: someone who already managed you decided you were worth more responsibility. That is meaningful evidence. The problem is that most candidates either collapse both roles into one entry or list them as two unconnected jobs, and both approaches waste the signal.
The Two Common Mistakes
Mistake 1: Collapsing everything into one title
Some candidates list only their final, higher title and write bullets that cover the full tenure. This hides the fact that there was a promotion at all. A reader has no idea you started junior and earned your way up.
Mistake 2: Listing the same employer twice as separate jobs
This makes a promotion look like a job change. It breaks the visual flow, takes up extra space, and can confuse ATS systems that try to calculate tenure.
The Format That Works
Use a stacked entry under one employer header. The company name and total date range sit at the top. Each title gets its own sub-entry with its own date range and its own bullets.
Here is what that looks like:
Acme Marketing, Chicago, IL | June 2024 to Present
Marketing Coordinator | Jan 2025 to Present
- Led weekly content calendar for three product lines, reducing missed deadlines from four per quarter to zero.
- Trained two new interns on the scheduling tool and internal review process.
Marketing Assistant | June 2024 to Jan 2025
- Drafted social copy for paid campaigns averaging 8,000 impressions per post.
- Compiled weekly performance reports for the senior team.
This structure does several things at once. It shows tenure at one company (good for ATS tenure calculations). It makes the promotion visible at a glance. And it lets you write bullets that are honest about what you did at each level, rather than blending junior tasks with senior ones.
What to Write in the Bullets for Each Level
The lower title should show what you were doing and doing well. The higher title should show what changed: bigger scope, more ownership, managing others, or leading a process instead of supporting it.
If the responsibilities barely changed, be honest about that. You can still show growth by pointing to scale, autonomy, or results that came after you had more context.
- Lower level: "Supported campaign reporting by pulling weekly data from the analytics dashboard."
- Higher level: "Redesigned the reporting template, cutting prep time by roughly half and making the format usable for client-facing decks."
The shift from supporting to owning is the story. The stacked format makes sure a reader sees it.
A Note on Timing
If you were promoted after a short stint, say five months, include the dates. A fast promotion is a data point in your favor. Do not round up to make it look longer. Specificity reads as honest, and vagueness reads as a reason to look harder.
The stacked entry takes about ten minutes to set up and pays off every time a recruiter scans your work history looking for signs that someone else already bet on you.
