A practice prompt we wrote. No company or candidate report names it, so it carries no company tag.
How to answer
Baseten’s (Training) posting, as of September 2026, asks for willingness to respond to customers outside regular working hours and to join an on-call rotation. Source 1Forward Deployed Engineer (Training) @ BasetenPublisherBaseten (Ashby)Source typecompany job posting This question checks whether you have done that job, and the words “owned personally” and “last follow-up” set the bar.
Tell it as a timeline, and at each stage say two things: what you did, and what the customer was experiencing at that moment.
- The alert. How it reached you, when, and who noticed first. If the customer found it before your monitoring did, say so now; it sets up the prevention at the end.
- First contact. How fast you reached the customer, the words you used, and when you promised the next update. Naming yourself as the single owner belongs here.
- Containment before cause. What you did to stop the damage before you understood it, and what the customer could do in the meantime.
- The fix. One or two sentences on the cause and the repair.
- The close. The written summary, the commitments with dates, and the last follow-up: the conversation weeks later where you showed the prevention working.
Say your update cadence out loud, including the update with no news in it: “I’d promised an update at one, and I sent it at one, though all I could say was that the fix was still running.” Kept small promises are how the customer learns to trust the large one.
Keep the root cause short. Interviewers who want the debugging will ask, and the question’s weight is on the customer.
The trap is the war story where the customer vanishes after the first paragraph. The second is ending at the fix, when the question runs explicitly to the last follow-up.
Follow-ups
What the interviewer may ask next, once your first answer is on the table.
- Who noticed first, you or the customer, and what would have let you notice first?
- Why did a model update reach her ledger without a regression check, and whose call was that?
- Which follow-up commitment was hardest to keep, and did it ship on the date you gave?
Where answers go wrong
- Tells a debugging story in which the customer disappears after the first alert, so the communication and the follow-through go unanswered.
- Ends at the fix; the written close and the last follow-up, which the question names, never appear.
- Picks an escalation someone else ran and describes it as “we”, so the interviewer cannot tell what the speaker owned.

Illustrative answer about a fictional project
I ran invoice extraction for a freight broker: carrier invoices came in as PDFs, we extracted the amounts, and they posted to the broker’s accounts payable system for a weekly payment run on Thursdays. At 8:10 on a Tuesday the AP manager emailed our account lead: carrier totals looked low in the payment preview.
