What this question tests
Tests competitive strategy against both an AI native rival and entrenched incumbents in the same market.
How to approach it
- Map the competitive set clearly: Decagon as an AI native peer, Zendesk and similar as incumbents with existing customer relationships and ticketing infrastructure.
- Identify Sierra's actual advantage: outcome based pricing and an agent architecture built for full resolution, not ticket deflection.
- Identify the incumbent's advantage: existing enterprise contracts, integrations, and trust built over years, which is hard to displace with features alone.
- Propose a wedge strategy: target high volume, well defined workflows first, like order status or returns, where full resolution is provable and ROI is easy to show.
- Propose a defense against Decagon specifically: compete on reliability and vertical depth rather than a feature race, since AI native rivals can copy features fast.
- Confirm with the interviewer whether the focus is winning net new logos or displacing Zendesk inside existing accounts, since the playbook differs.
What a strong answer includes
- Anchors the strategy on Sierra's outcome based pricing as a structural differentiator incumbents cannot easily match without cannibalizing seat based revenue.
- Proposes proving ROI in a narrow, measurable workflow before expanding scope, which builds trust faster than a broad feature comparison.
- Distinguishes the Decagon fight, which is about execution speed and reliability, from the Zendesk fight, which is about displacing an entrenched system of record.
- Suggests partnering with or sitting alongside existing ticketing systems initially, lowering switching cost rather than demanding a full rip and replace.
Common mistakes
- Treating Decagon and Zendesk as the same kind of competitor when the strategy against each is different.
- Leading with a feature list instead of the pricing model and reliability advantage that are harder to copy.
- Ignoring switching cost, which is often the real barrier to displacing an incumbent like Zendesk.
Likely follow-up questions

- Traffic is growing, p95 agent latency is degrading, and GTM is asking for faster delivery of customer-specific features. As PM for Infrastructure, how would you decide what to do in the next quarter: performance work, reliability hardening, cost optimization, or platform investments that unblock product teams?

- You have separate 30-minute meetings with a CIO and an engineering lead at the same prospect. How would you change the demo, proof points, and objections you address for each audience while keeping the core product story consistent?Sierra · Strategy · Medium
- Three enterprise customers request similar capabilities, but each wants different workflow details. How would you decide whether to build a one-off feature, create a reusable platform capability, or advise a process workaround instead, and what criteria would drive the roadmap decision?Sierra · Strategy · Hard
- Early design partners want very different things from the SDK: one wants deep customization, one wants the fastest possible integration, and one wants better monitoring and debugging tools. With limited engineering capacity, how would you decide what to build first?Sierra · Strategy · Medium
