Unlocking Design Influence: Lessons from a Real‑World Interview Case

Have you ever been midway through revising a design when the requirements suddenly change, or felt treated merely as a tool while endless debates over design details drag on? These symptoms indicate low design authority. This article analyzes a real case to share secrets for deepening design thinking, imagination, and impact.

In daily work, designers interact most with product managers (PMs). Some designers refine directly from the PM’s prototype, saving time but risking shallow solutions. Others first explore the background and goals before tackling the specifics, often producing markedly different outcomes.

Which approach is better? Consider the classic story of Ford asking people what they wanted in a better vehicle—most answered “a faster horse.” The “better vehicle” represents the need, “faster” the expectation, and the “horse” the assumed solution. Similarly, a PM’s prototype is a hypothesis whose validity depends on the PM’s understanding and breadth of thinking.

The case shared here involves an online interview scenario for a domestic‑service platform. The platform matches clients with caregivers (referred to as “aunties”). During interviews, clients ask about the caregiver’s experience and skills. The PM proposed adding guided Q&A prompts to help caregivers respond accurately, hoping to boost satisfaction and conversion.

Analysis shows that a one‑to‑one Q&A guide raises the client’s cognitive load and disrupts the immersive interview experience, while caregivers may feel overwhelmed by dense on‑screen text. Consequently, the PM abandoned this hypothesis.

To truly solve the problem, we must identify its essence: the core factor in conversion is the human element. Understanding real user needs is essential for valuable features.

We start from the user’s perspective: imagine yourself as the client, then as the caregiver. Clients, after reviewing caregiver profiles, seek hidden traits—personality, communication, adaptability—during the interview. Caregivers aim to showcase strengths but face time pressure, varied client expectations, and limited expressive ability.

From this dual‑role analysis, four key interview pain points emerge: (1) uncovering hidden caregiver traits, (2) improving interview efficiency, (3) providing memory‑aid tools, and (4) enabling caregivers to express themselves fully.

Solution brainstorming follows the interview workflow: pre‑interview, during the interview, and post‑interview. Pre‑interview, provide clients with quick‑access trait guides and allow them to add custom questions to a “to‑ask list.” Offer video résumés of caregivers for initial impressions. During the interview, equip caregivers with targeted preparation tips based on client profiles and introduce memory‑aid features such as screen recording and expandable question lists. Post‑interview, deliver replay functionality and a scoring rubric for clients, enabling side‑by‑side comparison of caregivers to facilitate decisive choices.

Finally, when receiving a new requirement, avoid jumping straight to sketches. Follow these steps: (1) Identify the underlying demand aligned with business goals; (2) Empathize by reconstructing user scenarios to pinpoint key influencing factors; (3) Switch to an expert viewpoint, map the business process, leverage existing resources, and propose valuable, implementable solutions.

Cultivating deep‑thinking habits helps designers shed the “tool” label, strengthen design voice, and become indispensable experience advocates for both business and team.
