Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
01
Evaluation factor
Portfolio
35% weight
Ask for live campaign examples: lifecycle flows, promotional blasts, newsletters. Look for before and after templates, brands worked on, and click-through or conversion lifts they can attribute.
Evidence to listen for
Work exists and can be looked at, not just described
States what they made versus what the team or a template made
Shows range rather than one repeated style
Can walk through a piece from brief to final
Five-point scoring guide
1
Poor
No portfolio, or work that is unattributable or clearly templated.
2
Needs Improvement
Thin portfolio; unclear what they personally made.
3
Satisfactory
Real work with adequate range; contribution mostly clear.
4
Very Good
Strong varied portfolio with clear personal ownership.
5
Excellent
Shows real sends across Klaviyo, Braze or Marketing Cloud with rendered screenshots and open, click and revenue figures per campaign.
02
Evaluation factor
Craft and rationale
25% weight
Probe how they build: Figma to MJML or hand-coded table layouts, hybrid responsive techniques, dark mode handling, Outlook Word rendering engine quirks, and alt text plus semantic accessibility.
Evidence to listen for
Explains why a layout, type choice, or colour decision serves the brief
Knows typography and hierarchy as craft, not decoration
Works to a brand system without either breaking it or hiding behind it
Names the tools they are genuinely fast in
Five-point scoring guide
1
Poor
Cannot explain any decision; work is arbitrary.
2
Needs Improvement
Talks in taste terms only; no link between choice and brief.
3
Satisfactory
Sound craft with some ability to justify decisions.
4
Very Good
Articulate about why each choice serves the brief.
5
Excellent
Explains specific fixes for Outlook conditional comments, retina images and dark mode inversion, and defends layout choices against inbox constraints.
03
Evaluation factor
Feedback and iteration
25% weight
Test how they respond to Litmus or Email on Acid failures, brand team notes and A/B test losses. Ask about a design they revised after subscriber data contradicted it.
Evidence to listen for
Takes critique without treating it as an attack
Distinguishes a subjective preference from a real problem, and says so politely
Iterates fast rather than defending version one
Delivers files correctly and on time
Five-point scoring guide
1
Poor
Defensive about critique; will not revise.
2
Needs Improvement
Accepts feedback passively; iterations do not improve the work.
3
Satisfactory
Revises willingly; struggles to push back on weak feedback.
4
Very Good
Iterates quickly and can argue for the work when the feedback is wrong.
5
Excellent
Describes iterating a hero or CTA after variant testing, citing the metric shift, and separates personal taste from evidence.
04
Evaluation factor
Working with the brief
15% weight
Assess intake with lifecycle marketers and merchandisers: campaign calendars, modular template systems, asset deadlines, and how they handle late copy or shifting promo dates.
Evidence to listen for
Asks about audience and goal before opening the design tool
Works with marketing, product, or clients rather than in isolation
Flags an impossible brief early
Hands over files and assets others can actually use
Five-point scoring guide
1
Poor
Designs in isolation; ignores the brief's purpose.
2
Needs Improvement
Starts designing before understanding the goal.
3
Satisfactory
Asks the right questions when prompted.
4
Very Good
Interrogates the brief up front and hands over cleanly.
5
Excellent
Runs a reusable modular component library, clarifies segment and offer before designing, and consistently ships to the send calendar.
