What this question tests
Trade-off reasoning between user experience and infrastructure constraints under a real operational request.
How to approach it
- Clarify the trigger: an ISP-level bandwidth crunch, as happened in 2020 with EU regulators, requiring a cut to average bitrate.
- Identify affected users: everyone, but disproportionately those already on lower bandwidth or shared connections.
- Decide the lever: default to a lower max bitrate rather than removing quality options entirely.
- Preserve user control: keep a manual high-quality toggle for users who want it and can afford the data.
- Communicate transparently why quality changed temporarily, avoiding silent degradation that erodes trust.
- Define success as total bandwidth reduction achieved versus change in rebuffer rate and complaints.
What a strong answer includes
- References the real 2020 EU precedent, showing grounded knowledge rather than guessing.
- Balances the operational ask against user trust by proposing an opt-out rather than a forced blanket downgrade.
- Gives a measurable trade-off: cutting average bitrate 25% may meaningfully reduce bandwidth demand while most users on smaller screens won't notice.
Common mistakes
- Only optimizing for the bandwidth ask and ignoring perceived quality drop.
- Not proposing any user communication or opt-out mechanism.
Likely follow-up questions
- How would you decide which markets to prioritize the cut in?
- How would you know if users actually noticed the quality drop?
