Behavioral

Describe a time when you had to convince stakeholders to adopt a new disease surveillance protocol.
Situation

While working at a state health department, our existing influenza surveillance relied on passive reporting, leading to delayed outbreak detection.

Task

I was tasked with proposing an active, electronic reporting system and securing buy‑in from hospital administrators, clinicians, and the state health director.

Action

I gathered data on timeliness gaps, built a cost‑benefit model, presented pilot results from a neighboring county, and organized workshops to address concerns about workflow and data privacy.

Result

The stakeholders approved a phased rollout; within six months, reporting lag dropped from 14 days to 3 days, and we identified two seasonal spikes earlier, enabling timely public health interventions.

Follow‑up Questions
  • What metrics did you track to measure success?
  • How did you handle resistance from clinicians?
  • Would you implement the same approach for a different disease?
Evaluation Criteria
  • Clarity of problem definition
  • Use of data and evidence
  • Stakeholder engagement strategy
  • Measurable outcomes
Red Flags to Avoid
  • Vague results or no numbers
  • Blaming others
Answer Outline
  • Explain context and problem
  • State your responsibility to improve surveillance
  • Detail data‑driven proposal and stakeholder engagement
  • Quantify impact on reporting speed and public health response
Tip
Highlight specific quantitative improvements and emphasize collaborative communication.
Tell us about a project where you had to manage competing priorities during an outbreak investigation.
Situation

During a multi‑state measles outbreak, I was the lead epidemiologist coordinating case‑finding while the lab was overwhelmed with COVID‑19 testing.

Task

Balance rapid case verification, contact tracing, and public communication without compromising data integrity or ethical standards.

Action

I instituted a triage protocol prioritizing high‑risk contacts, delegated data entry to trained interns, secured an emergency IRB amendment for expedited data sharing, and held daily briefings with the lab and communications team to align expectations.

Result

We confirmed 87% of suspected cases within 48 hours, traced 1,200 contacts, and reduced secondary transmission by 30% compared with the previous year’s outbreak.

Follow‑up Questions
  • How did you ensure data privacy under pressure?
  • What would you do differently if resources were even scarcer?
Evaluation Criteria
  • Prioritization logic
  • Ethical considerations
  • Team coordination
  • Outcome quantification
Red Flags to Avoid
  • Lack of specific actions or outcomes
Answer Outline
  • Set the scene of simultaneous high‑stakes tasks
  • Define your role in prioritization
  • Describe concrete steps taken to allocate resources and maintain ethics
  • Provide outcome metrics
Tip
Show structured decision‑making and ethical vigilance under pressure.
