Product design question
You are responsible for building an education platform that connects people looking to learn new skills with experienced individuals who can teach them (such as pottery, welding, piano, math, etc.). Essentially, it's a shared economy for skills. How would you approach this task?

What this question tests
Two sided marketplace design skill: can you solve trust, discovery, and quality verification for a skills sharing economy across very different skill categories.
How to approach it
- Define both sides: learners seeking hands on skills like pottery or piano, and teachers who are often solo practitioners without formal certification.
- Identify the core challenge, trust in teacher quality varies wildly across unrelated categories, unlike a single vertical marketplace.
- Prioritize a lightweight verification and review system over heavy certification requirements, since most teachers will not have formal credentials.
- Design the core flow: teacher profiles with sample work or short intro videos, learner reviews after each session, and a booking and messaging system.
- Start narrow, launch with two or three high demand categories like cooking and music, rather than all skills at once, to build supply density.
- Define success as completed sessions per teacher and repeat booking rate, since repeat use signals real trust was built.
What a strong answer includes
- Recognizes trust verification differs by category and proposes lightweight, scalable mechanisms like reviews rather than expensive certification.
- Scopes the launch to a few categories first, a realistic sequencing decision for a broad marketplace idea.
- Picks repeat booking as the key metric, since it is the clearest signal of real trust and satisfaction.
Common mistakes
- Trying to launch across all skill categories at once, which spreads supply too thin to build trust anywhere.
- Proposing heavy certification requirements that would exclude most real world teachers, like a retired welder.
Likely follow-up questions
- Which two categories would you launch with first and why?
- How would you handle a dispute over teaching quality after a paid session?
