What this question tests
Product improvement thinking for a freemium hardware-adjacent service with a clear conversion funnel from free to paid.
How to approach it
- Clarify the users: business travelers who value speed, leisure travelers who are price sensitive, and airport staff or airlines as partners.
- Map the current funnel: free 30 minutes, then a paywall, and identify where drop-off likely happens.
- Identify pain points, such as the paywall appearing without warning or coverage being spotty near gates.
- Propose improvements: a countdown warning before the free period ends, tiered pricing (1 hour vs. full-day vs. multi-airport pass), and partnerships with airline loyalty programs for free upgrades.
- Prioritize the change most likely to lift conversion without hurting the free-tier experience that builds trust.
- Define a success metric, such as paid conversion rate or average session length past the free window.
What a strong answer includes
- Identifies a concrete friction point, like an abrupt cutoff, and fixes it with a clear warning and one-tap upgrade.
- Proposes segmented pricing, such as a day pass for travelers with layovers versus a short paid block for quick users.
- Considers a loyalty or airline partnership angle since airport Wi-Fi has a natural B2B2C structure.
- Notes that free tier quality (speed, reliability) must stay strong since it is the trial for paid.
- Gives an assumption-based estimate of what percent of free users might convert with a smoother upgrade flow.
Common mistakes
- Suggesting to remove the free tier entirely without weighing brand and airport-contract implications.
- Ignoring that airports often mandate the free-Wi-Fi minimum by contract.
Likely follow-up questions
- How would you price a multi-airport annual pass?
- How would you test the countdown-warning idea before full rollout?
- How would airline partnerships change your pricing model?
