User Research
At my previous company we were redesigning the checkout flow for an e‑commerce site with limited budget and a tight deadline.
I needed to determine the most effective research method to uncover pain points without delaying the launch.
I evaluated options—surveys, contextual interviews, and usability testing—considering cost, time, and depth. I chose remote contextual interviews combined with a short survey to quickly gather qualitative insights and quantitative validation.
We identified three critical friction points, prioritized them, and delivered a redesign that increased checkout completion by 12% within two weeks of launch.
- What metrics did you track to measure success?
- How did you recruit participants for the interviews?
- Clarity of problem definition
- Rationale for method selection
- Impact on product outcomes
- Vague description of methods
- No measurable results
- Explain project context and constraints
- State the decision goal
- Describe evaluation of methods
- Justify chosen method
- Highlight impact of findings
During a redesign of a SaaS dashboard, the research team delivered a 30‑page report that stakeholders found overwhelming.
My role was to translate findings into clear, actionable recommendations for the design team and executives.
I synthesized insights into personas, journey maps, and a prioritized list of pain points with suggested design solutions. I presented findings in a workshop, using visual storytelling and linking each recommendation to a business metric.
Stakeholders approved the roadmap within a day, and the design team implemented the top three recommendations, resulting in a 20% reduction in task completion time.
- Can you share an example of a visual artifact you created?
- How do you handle conflicting stakeholder opinions?
- Use of visual tools
- Prioritization logic
- Stakeholder engagement
- Overly technical language
- Lack of prioritization
- Summarize findings concisely
- Create visual artifacts (personas, journey maps)
- Prioritize insights with business impact
- Provide concrete design suggestions
- Facilitate interactive workshops
Design Process
We were tasked with adding a 'saved items' feature to a mobile shopping app.
Deliver a user‑centered solution from concept to handoff.
I started with stakeholder interviews to define goals, followed by competitive analysis. I then conducted user interviews and created affinity maps. Based on insights, I sketched low‑fidelity wireframes, iterated them in usability tests, and refined into high‑fidelity prototypes using Figma. Finally, I documented specs and handed off to developers with a design system checklist.
The feature launched on schedule, achieving a 15% increase in repeat purchases within the first month.
- What tools did you use for prototyping?
- How did you handle design system constraints?
- Logical flow
- User‑centered decisions
- Collaboration points
- Skipping research steps
- Vague handoff process
- Stakeholder alignment
- User research & insights
- Ideation & sketching
- Low‑fidelity testing
- High‑fidelity prototyping
- Design handoff
During a redesign of the onboarding flow, senior engineering leadership argued that my proposed multi‑step wizard would increase development time.
Defend the design while addressing technical concerns and maintaining user experience quality.
I prepared data from usability tests showing a 30% drop‑off with the existing flow. I collaborated with engineers to map the wizard onto existing components, identifying reusable modules. I offered a simplified version with fewer steps as a compromise and documented the trade‑offs.
The team adopted the simplified wizard, reducing onboarding friction by 22% and staying within the development timeline.
- What metrics did you use to measure onboarding success?
- How did you ensure the final design met accessibility standards?
- Evidence‑based advocacy
- Collaboration approach
- Flexibility
- Defensive tone
- Lack of data
- Present data‑driven justification
- Engage cross‑functional partners
- Propose alternatives
- Document trade‑offs
Collaboration & Communication
In a cross‑functional project to redesign a health‑tracking app, product, marketing, and legal teams each had strong opinions on data presentation.
Synthesize feedback while keeping the core user experience intact.
I facilitated a stakeholder workshop to surface underlying goals, then mapped each request to user needs and regulatory requirements. I created a prioritized feedback matrix, highlighting which suggestions aligned with user research and which conflicted. I presented trade‑offs and proposed a modular design that allowed optional features without cluttering the main flow.
The final design satisfied all teams, received a green light from legal, and user testing showed a 10% increase in daily active users.
- Can you give an example of a conflicting request and how you resolved it?
- How do you document decisions for future reference?
- Structured feedback handling
- User‑first mindset
- Clear communication
- Ignoring stakeholder concerns
- No documentation
- Stakeholder workshop
- Feedback matrix
- Align with user research
- Propose modular solution
On a six‑month redesign of an enterprise dashboard, the design specs quickly became outdated as features evolved.
Implement a sustainable documentation workflow.
I adopted Figma's component library with version control, linked design specs to Confluence pages, and set up a weekly sync with developers to review changes. I also created a living style guide that auto‑updates from the design system.
Documentation lag dropped from weeks to days, reducing design‑dev rework by 18% and improving release predictability.
- How do you handle undocumented ad‑hoc changes?
- What metrics do you track to gauge documentation health?
- Tool proficiency
- Process rigor
- Collaboration cadence
- No concrete process
- Reliance on manual updates
- Tool selection (Figma, Confluence)
- Version control process
- Regular sync meetings
- Living style guide
- user research
- wireframing
- prototyping
- usability testing
- interaction design
- Figma
- design systems
- persona development
- A/B testing
