How to answer
Some employers write this loop into the role. OpenAI’s San Francisco posting, as of September 2026, says its FDEs measure success partly through “eval-driven feedback that changes product and model roadmaps.” Source 1Forward Deployed Engineer (FDE) - SFPublisherOpenAI CareersSource typecompany job posting Ramp’s Software Engineer, Forward Deployed posting for its Core FDE org, as of September 2026, says its FDEs drive the core product engineering roadmap by specializing in one core product area and deciding when to build a custom solution and when to speed up a broader initiative.

Plan for the second half: “how did you make the case” asks how you persuaded a team that owed you nothing. Five moves:
- The signal. What you saw at one customer, as an observation, not a feature request: “They had three people copying approvals into a spreadsheet.”
- The pattern. How many customers, and how you checked: other deployments’ code, support tickets, a message to the other FDEs. Separate the need from the solution each customer asked for.
- The cost of doing nothing, in the product team’s terms. Engineering weeks on one-off workarounds, deals stalled, renewals at risk, support load.
- The proposal. The smallest product change that covers most cases, what you brought to it (a prototype, test data, design-partner customers), and the one decision you asked for.
- What changed. What they decided, what they gave up for it, when it shipped, and what happened to the one-off versions.
Say the count early, as a number of deployments, not “several customers”. The number moves you from advocate to evidence.
Find out what the product team already committed to, and ask for a swap, not a new priority on top.
The trap is the loud-customer story. If one large customer drove it, say so, and what made it right for the others.
Follow-ups
What the interviewer may ask next, once your first answer is on the table.
- How did you tell a pattern across customers from one loud customer?
- What did the product team push back on, and were they right about any of it?
- What did you keep building for customers as a one-off while you waited, and what happened to it once the product change shipped?
Where answers go wrong
- Tells the story of one customer’s request that the product team happened to build, with no evidence of a pattern and no case beyond “the customer really wanted it”.
- Treats filing a ticket or raising it in a channel as making the case, and never says what the product team decided, what they traded away for it, or what shipped.

Illustrative answer about a fictional project
I was a forward deployed engineer at a company that sold an AI support agent to retailers. At my third deployment, a home-goods retailer, the support director wouldn’t let us change the agent’s instructions without a week of manual testing: two of her staff replayed about 80 old conversations by hand and compared answers in a spreadsheet.
