How to Answer Competency-Based Interview Questions for UN Jobs
UN interviews are structured and competency-based. Here's how to prepare STAR-format answers, which competencies come up most often, and what panel members are actually evaluating.
How to Answer Competency-Based Interview Questions for UN Jobs
The UN system's hiring process is almost universally competency-based. Panel interviews follow a structured format where every candidate is asked the same predetermined questions, and answers are scored against a defined rubric. Understanding how this works — and preparing properly — makes a decisive difference to your outcome.
What Is a Competency-Based Interview?
A competency-based interview assesses your past behaviour as a predictor of future performance. Rather than asking hypothetical questions ("What would you do if…"), panel members ask you to describe specific situations you have actually experienced: "Tell me about a time when…"
The assumption is that demonstrated past behaviour in a relevant situation is the best evidence of how you will behave in a similar situation in the future.
The STAR Method
Every competency answer should follow the STAR structure:
- Situation: briefly set the scene — where, when, what was happening
- Task: your specific responsibility in that situation
- Action: what you personally did — use "I", not "we"
- Result: what happened as a result of your actions — be specific and quantify where possible
The most common mistake is spending too long on the Situation and not enough on the Action and Result. Panel members are scoring your actions and their impact — not your ability to describe a context.
Core Competencies You Will Be Asked About
Every UN agency publishes its competency framework, but the following appear across almost all of them:
Communication
Explaining complex ideas clearly; adapting your communication style for different audiences; active listening. Prepare examples of presenting to government officials, writing donor reports, or facilitating community meetings.
Teamwork and collaboration
Working effectively with colleagues from different cultural backgrounds; managing disagreement constructively. Prepare examples of cross-cultural team projects and how you handled different working styles.
Planning and organising
Managing competing priorities; meeting deadlines under pressure; adjusting plans when circumstances change. Prepare examples of multi-task project management.
Results focus / Delivering results
Taking ownership; driving outcomes even without authority; showing initiative. Prepare examples of going beyond your job description to get something done.
Innovation and change
Proposing new approaches; adapting to changing contexts; learning from failure. Prepare examples of introducing a new process or approach that improved results.
UN-Specific Competencies
Some agencies add specific competencies reflecting their mandate:
- UNICEF: commitment to continuous learning; working with children and vulnerable populations
- WFP: resourcefulness; managing under pressure in field settings
- UNHCR: commitment to humanitarian principles; managing protection risk
Practical Preparation Tips
1. Re-read the job description the day before: identify which three or four competencies are most emphasised and prepare one to two STAR examples for each
2. Write out your examples before the interview — this forces clarity and helps you remember them under pressure
3. Quantify your results: "we reached 15,000 beneficiaries", "I managed a $2.3M budget", "the programme was delivered six weeks ahead of schedule"
4. Practise out loud: STAR answers that read well on paper often come out as rambling when spoken unprepared
5. Have a backup example for each competency: panel members sometimes ask follow-up questions that require a second example
After the Interview
UN hiring processes are slow. Six to twelve months between interview and offer is normal. Sending a brief thank-you note within 24 hours of the interview is appropriate and not common — it helps the panel remember you. After that, wait and continue applying to other roles.
