What a strong answer covers

Try it out loud first. Then check yourself:

  1. Open an incident; loop in legal, privacy, HR and comms. Preserve the vendor notice and request IOCs and a timeline.
  2. Cut exposure: rotate API keys/SSO certs to the vendor, review integration logs for anomalous pulls or logins.
  3. Confirm scope: which records, which fields, date range. Map to state breach laws and any GDPR notification duty.
  4. Protect people: notify employees, offer credit monitoring, warn about payroll-diversion phishing targeting them.
  5. Afterwards: invoke contract clauses (notice SLA, costs), reassess vendor tier, and document in the risk register.

If the interviewer pushes back

  • The vendor says it cannot confirm whether your tenant was affected. Do you notify employees anyway? Why?
