AI The migration you ran in February. You said the rollback
worked but the team had a difficult week. Walk me through
what made it difficult.
CANDIDATE We did not have a clean fail signal on the new path. The
metric we were watching lagged by about 40 minutes. So we
spent that window thinking it was working before realising
it was not.
AI What changed about how you measure rollouts after that?
CANDIDATE We added a real-time canary on the request path, not just
the metric. And we added a kill switch that does not need
a deploy to flip. Two changes, both small.
AI If you joined this team and saw a rollout going sideways
on a Friday afternoon, what would you do in the first ten
minutes?
CANDIDATE The first thing is not technical. Get someone
in the loop who knows the system and is not me. Then the
kill switch if we have one. Then a clear comms message to
the team about what we are doing and what to stop doing.
Then the diagnosis...Before the interview starts, the candidate sees a clear opt-out: a human interviewer instead of the AI, no penalty, no flag in the file. The same questions, the same rubric, conducted by a Picked-trained recruiter at a scheduled time. Roughly 3 percent of beta candidates have used this; that is the cost of trust we are willing to pay.
