I would make your existing working-holiday quiz quite substantial because it could become one of your highest-value quizzes.

Instead of superficial questions like “Do you prefer beaches or mountains?”, include actual decision factors:

• maximum budget before departure
• whether they want to find work quickly
• city versus rural work
• climate
• earning potential
• backpacking opportunities
• whether English-speaking environment matters
• public transport
• whether they want one base or constant travel

Then results such as Japan / Canada / Australia / New Zealand / South Korea etc. can link directly into your established working-holiday silos.

That creates:

Quiz → country hub → visa guide → arrival guide → accommodation/insurance/etc.

That’s exactly the kind of user journey you’ve been trying to build.
