A practice prompt we wrote. No company or candidate report names it, so it carries no company tag.
How to answer
Leo Mehr, Ramp’s Director of Engineering, wrote in an August 2025 post on Ramp’s engineering blog, about its team, that when recruiting for the role, what matters most is “drive, communication, and the will to solve customer problems end-to-end.” Source 1Forward Deployed Engineering (Leo Mehr, Director, Engineering)PublisherRamp Builders (engineering blog)Source typecompany blog On Basil Chatha’s podcast in July 2026, speaking about hiring in general, he said he assesses ownership by asking candidates about the decisions they made and what they were responsible for.

This question probes both. It has two halves, and the second is the one to plan for. “First conversation to production” asks for scope, end to end. “Which decisions were yours alone” asks you to separate your judgment from the team’s work, so prepare for the same probe Mehr describes, at project level: which calls were yours.
Five steps, with most of your time on the third:
- The customer and the pain, in two sentences. Who they were, what hurt, and what it cost them. No company history.
- The first conversation. What they asked for, and what you found they needed. The gap between the two is what makes this an FDE story rather than a ticket story.
- Your decisions, counted and named. For each: the options, the one chosen, and what it cost. Separate the calls you made from the calls you recommended and someone else approved; expect a follow-up on exactly that line. Two to four is right. One sounds thin; a long list sounds like the team’s work relabeled.
- Production and after. What shipped, who used it, the number that moved, who measured it, and who owns it now that you have gone.
- What you would change. One decision you would make differently now.
Draw the boundaries out loud: “The data pipeline and the rollout plan were mine; Dana built the dispatcher board.” Crediting a colleague by name makes your own claims easier to believe.
Hold back the architecture and the proof that your change caused the result. Name each in a clause and give the detail when asked; the follow-ups are where it earns credit.
The trap is answering the first half and skipping the second. Hear the difference:
- Weak: “We scoped it, we built a pipeline on the telematics data, and we cut late pickups.”
- Strong: “I chose ignition and geofence events over a driver app. The head of dispatch approved dropping the optimizer on my evidence.”
The tour in “we” leaves the listener to guess which part was yours. If a decision was shared, say so, and say what your part of it was.
Follow-ups
What the interviewer may ask next, once your first answer is on the table.
- Which of those decisions would you make differently with what you know now?
- What did the customer push back on, and how did you settle it?
- Who measured the result, and how do you know your change caused it?
Where answers go wrong
- Tours the whole project in “we” and never says which calls were theirs, so the ownership has to be dug out one follow-up at a time.
- Spends most of the answer on background and architecture, leaving a sentence at the end for the decisions and no measured result.

Illustrative answer about a fictional project
Written in the first person to show the structure. Tell yours from your own work.
I was the lead engineer on a six-week engagement with a regional freight company: 300 trucks, four depots, and about $40,000 a month in penalties for late pickups.
The head of dispatch asked for a route optimizer. Sitting with dispatchers, I found the routes were fine; nobody knew when a driver had finished a drop, because status came in by phone.
Three decisions.
The first was mine alone. I inferred driver status from ignition and geofence events on the telematics boxes already in the trucks. That’s noisier than a driver app, but nobody had to get 300 drivers to adopt one.
The second I recommended, and the head of dispatch made the call: drop the optimizer. On 70% of late pickups, the ignition data showed a truck that had finished its drop within 20 miles, so the routes weren’t the problem.
The third I proposed, and the operations director agreed: pilot at one depot first.
Dana, the other engineer, built the dispatcher board.
Over the eight weeks after rollout, their finance team measured late pickups falling from 11% of loads to 4%, and their operations analyst has run the rules since handover.
What I’d change: I piloted at the smallest depot because it was safest, so it couldn’t show the busiest depot’s problem: trucks queuing at the gate showed as busy. Now I pilot where the load is highest, with a rollback ready.
If asked how I know the change caused it: while the pilot depot ran alone, its late rate fell and the other three stayed flat.

In Pro, the customer outcome you’re proudest of pushes the same line harder: which part of a result was specifically you.
