Product design question
Design a self-serve integration platform for enterprise customers building AI agents across voice, chat, email, and SMS. What are the core product primitives you would include first, and what tradeoffs would you make to balance power for technical users with simplicity for enterprise teams managing setup, permissions, testing, and ongoing maintenance?

What this question tests
Tests product design for a self-serve integration platform, balancing power-user flexibility with enterprise admin simplicity.
How to approach it
- Clarify the primary channel mix, voice, chat, email, SMS, since each has different setup and testing needs.
- Define core primitives first: a connection object per channel, a permission scope for what the agent can access, and a sandbox for testing before go-live.
- Design setup as guided defaults with an escape hatch, templates for common configurations plus raw config access for technical teams.
- Build permissioning around least privilege by default, admins grant scopes explicitly per channel and per data source.
- Include a test mode that mirrors production behavior without sending real messages, so teams validate before launch.
- Plan ongoing maintenance: versioned configs and a changelog so admins can roll back a bad change safely.
What a strong answer includes
- Names concrete primitives, a connection object, scopes, and a sandbox, rather than describing 'a flexible platform' abstractly.
- Balances power and simplicity explicitly with templates for common cases and raw access for advanced users, not one-size-fits-all.
- Treats maintenance and rollback as core to the design, since enterprise teams need to safely change configs after launch.
Common mistakes
- Designing only for technical power users and ignoring enterprise admin simplicity.
- No test or sandbox mode, forcing teams to validate against real customer channels.
Likely follow-up questions
- How would you handle a channel-specific failure, like SMS carrier filtering?
- How would you version and roll back a bad configuration change?

How would you scope a first production launch: which intents, channels, and member segments would you include or exclude; what escalation and approval rules would you set; and what evidence would you bring to get executive sign-off?Decagon · Product design · Hard

How would you choose the first 1-2 workflows, define the pilot scope, and set launch criteria so the deployment is compelling enough to win the deal, feasible to ship in 8-12 weeks, and expandable after launch?Decagon · Product design · Hard
