How to Prepare for a United Nations Interview

Understanding the UN Recruitment Process

The United Nations recruits across dozens of agencies — including the Secretariat, UNDP, UNICEF, UNHCR, and WHO — each with its own HR processes. That said, most follow a broadly similar multi-stage structure: an application and written assessment phase, followed by a competency-based interview, and in some cases a technical panel review.

Roles are typically advertised on Inspira (the UN Secretariat's jobs portal) or agency-specific platforms. Shortlisted candidates are assessed against the specific competency framework listed in the job opening, so reading that document carefully is the single most important preparation step you can take.

• Written tests: common for Professional (P) grade roles, often assessing drafting, analysis or technical knowledge
• Competency-based interviews: the core stage, usually conducted by a panel of two to four interviewers
• Technical interviews: relevant for specialist roles (IT, finance, legal, medical)
• One-way video screening: increasingly used by some UN agencies as an early-stage filter

The UN Competency Framework: What Interviewers Are Actually Assessing

The UN evaluates candidates against a defined set of core and managerial competencies rather than simply testing subject-matter knowledge. Core competencies commonly assessed across agencies include professionalism, communication, teamwork, planning and organising, accountability, and client orientation. Managerial roles add competencies such as leadership, vision, and empowering others.

Each job opening lists the specific competencies relevant to that post. Your entire interview preparation should be anchored to those competencies — not generic 'interview tips'. Download the job opening, highlight every competency listed, and plan at least one strong behavioural example for each.

• Professionalism: demonstrating subject expertise, commitment to UN values, and sound judgement
• Communication: conveying ideas clearly in both written and spoken form across diverse audiences
• Teamwork: collaborating effectively across cultures, functions, and hierarchies
• Planning and organising: managing priorities, resources and deadlines systematically
• Accountability: taking ownership of outcomes and following through on commitments

How to Use the STAR Method for UN Competency Questions

UN panel interviews are almost always behavioural in format: interviewers ask you to describe a specific past situation that demonstrates a listed competency. The STAR method — Situation, Task, Action, Result — is the most effective structure for these answers.

Keep each answer to roughly two to three minutes when spoken aloud. Interviewers are trained to probe, so expect follow-up questions such as 'What would you have done differently?' or 'How did your colleagues respond?' Practise answering those follow-ups, not just the headline story.

• Situation: briefly set the context — where, when, what was at stake
• Task: clarify your specific responsibility, not your team's collective role
• Action: focus on what YOU did — the steps, decisions, and reasoning
• Result: quantify the outcome where possible; if the outcome was mixed, show what you learnt

Example STAR Answer: Teamwork Competency

Question: 'Describe a time you worked effectively as part of a diverse team to deliver a complex project.'

Example answer: 'In my role as a programme officer at an international NGO [Situation], I was part of a five-person team tasked with coordinating a regional food-security assessment across three countries within eight weeks [Task]. Two team members were based in remote field offices with limited connectivity, and we had significant differences in working styles and expectations around deadlines. I took the initiative to schedule weekly video calls with a shared written summary for those who could not always join live, and I created a simple shared tracker so everyone could see progress without chasing emails [Action]. We delivered the final report on time; it was used to inform a donor funding decision worth approximately $2 million, and two team members specifically mentioned the coordination approach in their end-of-project feedback [Result].'

Common UN Interview Questions to Prepare For

While no interviewer's exact questions can be predicted, UN panels routinely probe the competencies listed in the job opening. Below are representative question types across commonly assessed areas. For each one, prepare a distinct, specific example — avoid reusing the same story for multiple competencies.

If you are applying for a role that involves managing staff, expect additional questions on conflict resolution, coaching, and decision-making under ambiguity.

• Professionalism: 'Tell me about a time you had to deliver high-quality work under significant time pressure.'
• Communication: 'Describe a situation where you had to explain a complex technical issue to a non-specialist audience.'
• Accountability: 'Give me an example of when you made a mistake at work. What did you do?'
• Client orientation: 'Tell me about a time you went beyond expectations to meet a stakeholder or beneficiary need.'
• Planning and organising: 'Describe how you managed competing priorities during a particularly demanding period.'
• Vision (managerial): 'Tell me about a time you identified a strategic opportunity and persuaded others to act on it.'

Practical Preparation Tips Before Your Interview

Preparation for a UN interview rewards depth over breadth. The panel is not looking for candidates who know every UN resolution — they want evidence that you can do the specific job, embody UN values, and work effectively in a multicultural environment. The following checklist covers the essential steps in the week before your interview.

If your interview includes a one-way video component — where you record answers to questions within a set time limit — the stakes around clarity and composure are even higher, since you cannot read the room or ask for clarification. Practising on a platform like ScreenReady, which simulates timed video interview conditions and provides AI feedback on your responses, can help you identify habits like filler words, poor pacing, or weak answer structure before the real thing.

• Re-read the job opening and highlight every competency and technical requirement
• Prepare two to three STAR examples per competency — variety protects you if a follow-up question rules out your first story
• Research the specific UN agency's mandate, current strategic plan, and any recent news or operational priorities
• Prepare a concise 'overview of experience' answer for the opening 'tell us about yourself' question — keep it to 90 seconds
• Prepare two or three thoughtful questions to ask the panel at the end
• Check your technology well in advance if the interview is remote: camera, lighting, microphone, stable internet
• Review the UN Charter's core principles and the Sustainable Development Goals, particularly those relevant to the role

On the Day: What to Expect and How to Present Yourself

UN panel interviews are typically formal and structured. The panel follows a standardised script to ensure fairness, which means interviewers may not react warmly even when you give a strong answer — this is normal procedure, not a negative signal. Stay composed, speak directly to the question asked, and do not volunteer information that strays from the competency being assessed.

After each answer, pause briefly and check: have you covered the Situation, the Action, and the Result? If you realise mid-answer that you have drifted into describing your team's actions rather than your own, gently redirect: 'My specific contribution was…'. The panel is assessing you, not your organisation.

If you are asked a question you do not immediately have an example for, it is acceptable to take a few seconds to think. Saying 'May I take a moment to think of the best example?' is far preferable to rushing into an unfocused answer. Authenticity and precision matter far more than speed.
