A sample answer to question 1

Walk me through a project from your portfolio, from the brief to the final outcome.

I'll take a redesign of an online booking flow for a dental group. The brief was to reduce drop-off, which was around sixty percent at the payment step. I started by reviewing analytics and session recordings in Hotjar, then ran eight moderated interviews and a short survey to understand why people abandoned. We learned that users didn't trust the price because extra charges appeared late. I mapped the journey, sketched options in a workshop with the product owner and developers, and built a mid-fidelity prototype in Figma. I tested it with six participants, found that the new price summary confused older users, and iterated. After launch, completion rose from forty to sixty-one percent over two months and support calls about pricing fell by a third. I was the sole designer, so I also wrote the handoff notes and checked the build against my designs.

Common mistake to avoid: Describing only visuals; Claiming team results as solely yours
