"A step-by-step guide to tackling structured competency-based interview questions used by the United Nations, Save the Children, and IRC."

Executive Summary & Takeaways

  • Understand the core UN competencies: Professionalism, Integrity, Respect for Diversity, and Teamwork.
  • Use the CAR (Context, Action, Result) or STAR (Situation, Task, Action, Result) methodology to structure responses.
  • Focus 70% of your answer on YOUR specific individual actions rather than group activities.
  • Prepare 5-6 versatile real-world scenarios covering conflict resolution, tight deadlines, and complex stakeholder engagement.

1. What is a Competency-Based Interview?

Competency-Based Interviews (CBI) are grounded in the principle that past behavior is the best predictor of future performance. Organizations like the United Nations, WFP, UNICEF, Save the Children, and FHI 360 rely heavily on structured CBIs.

Instead of asking hypothetical questions ("What would you do if...?"), interviewers ask for specific past experiences ("Give an example of a time when you..."). Interviewers score your answers against specific behavior indicators.

2. The STAR & CAR Framework

Structure your responses using the STAR method:

  • Situation (10%): Briefly set the scene, giving context regarding project location, team size, and background.
  • Task (15%): Define the exact goal, challenge, or problem that needed resolution.
  • Action (60%): Explain in detail the specific steps YOU took. Avoid using "We did", use "I initiated...", "I analyzed...", "I recommended...".
  • Result (15%): Share the tangible outcome, backed by numbers, indicators, or lessons learned.

3. Top UN & INGO Competencies Tested

Be prepared to demonstrate concrete evidence for key competencies:

  • Teamwork: Collaborating across diverse cultural and technical backgrounds.
  • Planning and Organizing: Managing competing priorities under tight project deadlines.
  • Communication: Tailoring messaging for rural community beneficiaries versus institutional donors.
  • Accountability: Taking personal responsibility for project deliverables and financial stewardship.

4. Sample Questions and Model Answers

Question: "Describe a situation where you had to work with a difficult community stakeholder to achieve a project milestone."

Model Response outline: Start with the field context (e.g. hygiene promotion in an IDP camp), outline the initial community resistance, detail your diplomatic engagement strategy (holding town hall dialogues, engaging respected elders), and conclude with the outcome (95% community participation rate achieved).
