Honestly, my manager flagged me on a Friday afternoon and said the payments team was underwater. I spent about 11 hours over the weekend tracing a race condition in their checkout flow. We got a fix deployed by Monday morning.
Candidate showed effort and follow-through, but the decision to engage came from a manager, not themselves.
Our checkout flow was throwing silent errors and nobody on the backend team had picked it up after 48 hours. I dug into the logs, traced it to a misconfigured API timeout, and patched it myself. Conversion rate recovered by the next morning.
Candidate self-directed after a 48-hour gap — reactive to inaction rather than to a self-noticed signal.
Our checkout flow was dropping roughly 12 percent of sessions silently. It sat in a grey zone between my team and payments. I flagged it in standup, pulled the logs myself, and traced it to a malformed header. I fixed it. Nobody had asked me to.
Candidate spotted an ambiguous problem independently, quantified it, and acted without prompting.
