What this question tests
Incident response and root cause thinking under a severe, sudden metric failure.
How to approach it
- Immediate step: verify the drop is real, not a tracking or analytics reporting bug, by checking a second independent data source.
- Check for an outage: confirm whether the site or app is actually down or returning errors for real users.
- Check recent changes: correlate the drop's exact timing with a recent deploy, DNS change, or third-party dependency failure.
- Check external factors: a blocked domain, a broken redirect, or a search engine deindexing event could cause a sudden 100 percent drop.
- Escalate immediately to engineering and infrastructure teams given the severity, this is an incident, not a routine investigation.
- Communicate status to stakeholders with a clear timeline for updates, then do a postmortem once resolved to prevent recurrence.
What a strong answer includes
- Treats a 100 percent drop correctly as an incident requiring immediate escalation, not a routine analysis task.
- Checks tracking or analytics failure first, a common false alarm cause that should be ruled out before deeper investigation.
- Proposes checking recent deploys and third-party dependencies as the most likely root cause for a sudden total drop.
Common mistakes
- Treating this like a normal metrics dip requiring slow, methodical analysis instead of urgent incident response.
- Not ruling out a tracking or analytics reporting failure first.
- No plan for stakeholder communication during the incident.
Likely follow-up questions
- What would be your very first action in the first five minutes?
- How would you prevent this kind of total outage from happening again?
