Company: Nexon
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Technical Screen
How do you come up with a new feature idea for a live-service game product? Describe a structured process for identifying opportunities, selecting the right user problem, and turning that into a feature concept.
### Constraints & Assumptions
- Feature ideas should come from user/player pain, business goals, and feasible execution, not random brainstorming alone.
- Consider live-service constraints such as retention, monetization health, player fairness, economy balance, event cadence, and production capacity.
- Use evidence before prioritizing a concept.
- Include metrics and guardrails.
### Clarifying Questions to Ask
- What is the goal: new-player activation, returning-player reactivation, engagement, monetization, social play, or retention?
- Which player segment is in scope?
- What recent data or player feedback triggered the need for new ideas?
- Are we designing a temporary event, permanent feature, or experiment?
### Part 1 - Identify The Opportunity
How would you find the right player problem?
#### What This Part Should Cover
- Inputs from cohort data, funnel analysis, telemetry, player research, reviews, support, community channels, competitive analysis, and strategy.
- Clear player segment and job to be done.
### Part 2 - Generate Feature Concepts
How would you translate the problem into candidate features?
#### What This Part Should Cover
- Multiple options before choosing one.
- Examples such as returner questline, catch-up pass, build recommendation, social re-entry prompt, or live event.
- Player value and business value.
### Part 3 - Prioritize And Validate
How would you select the right idea?
#### What This Part Should Cover
- RICE or impact/effort/confidence framework.
- Prototype, beta, A/B test, or limited event rollout.
- Risks such as economy inflation, pay-to-win sentiment, veteran-player resentment, or production cost.
### Part 4 - Define Success
What metrics would show whether the feature worked?
#### What This Part Should Cover
- Retention, session count, feature completion, conversion to regular play, satisfaction, revenue quality, and guardrails.
### What a Strong Answer Covers
- Shows a repeatable ideation process.
- Grounds ideas in evidence and player segments.
- Prioritizes with tradeoffs, not taste.
- Protects long-term game health.
### Follow-up Questions
- How would you avoid copying competitors blindly?
- What if whales love the feature but casual users hate it?
- How would you test without disrupting the game economy?
- What guardrail would make you stop the feature?
- How would you involve design and live-ops teams?
Quick Answer: Explain how a live-service game PM generates feature ideas from player pain, telemetry, community feedback, business goals, and production constraints. The solution covers segmentation, concept generation, RICE prioritization, validation, retention metrics, and game-health guardrails.
