Describe a difficult interaction you had with a customer.

In my first year, I supported an internal tool used by a customer operations team, and one user was really frustrated because a report kept failing right before their weekly deadline. On the call, I let them explain the full impact first and realized they weren't just annoyed by the bug—they were worried they'd miss a commitment to their manager. I told them what I understood, checked that I had it right, and then worked with a more senior engineer to confirm a temporary workaround while the fix was being investigated. I stayed on the thread, sent an update before the end of the day, and followed up again once the issue was resolved. After that, I started asking about business impact earlier in support conversations because it helped me respond in a way that was more useful and less reactive.

At a seed-stage startup I was the primary developer responsible for our new-user onboarding, and one small-business customer called furious because their identity documents kept getting rejected and they threatened to cancel. They were blunt and upset, so I listened without interrupting until they finished, then asked specific questions about what they'd uploaded so I could reproduce the problem. I discovered our validation rejected certain PDFs with embedded fonts, explained that limitation in plain terms, and offered a same-day manual verification so they could keep using the product immediately. I also issued a partial refund for the hassle and filed a clear bug report that the product manager prioritized for the next sprint. That experience taught me to pair quick human fixes with transparent communication and to advocate for fixes that reduce churn.
