UN competency-based interviews: preparing evidence from real work

A UN competency-based interview asks for evidence from past behaviour. The panel is trying to understand what the candidate did in a real situation, how the candidate acted and what followed.

The UN Careers interview guidance recommends a Situation, Action, Result structure. The official applicant guide says panels may ask for positive and negative examples and use probing questions until they have enough evidence.

Build examples from the opening

List the competencies named in the vacancy. Then choose real examples that show the behavioural indicators, technical responsibilities and level of the post.

One example can support more than one competency, but prepare alternatives. A teamwork story may not answer a later question about planning if the personal planning decisions are minor.

Use recent, substantial work where possible. Student and volunteer examples can be valid for early-career posts. Senior candidates should usually have evidence at the scale expected for the advertised grade.

Use Situation, Action, Result as a frame

Situation provides the context needed to understand the problem. Keep it brief: setting, objective, constraints and the candidate’s role.

Action is the main part. Explain personal decisions, sequence and reasoning. “We held consultations and delivered the project” hides the evidence. State whom you consulted, what disagreement arose, what options you considered and what you personally changed.

Result gives the outcome and how it was known. It can include delivery, a decision, feedback, data or a lesson. A result does not have to be perfect. Panels may ask about setbacks because reflection and corrective action reveal professional judgment.

The structure is a memory aid, not a script. Answers should sound responsive to the actual question.

Separate the candidate from the team

UN work is collaborative, and panels expect team results. They still need to assess one candidate.

Use “we” for the collective goal and “I” for personal responsibility. If the team produced a policy, explain whether you led research, drafted sections, negotiated clearance or approved the final text.

Do not upgrade participation into leadership. Serving on a task force is different from chairing it. Supporting a manager’s decision is different from holding delegated authority.

Prepare difficult examples

Questions can ask about conflict, failure, competing priorities, ethical concerns, feedback or a decision that would be handled differently now. Choose examples that contain a genuine problem and a professional response.

Avoid stories that blame colleagues or present a hidden success as a failure. Explain the information available at the time, the action taken, its consequences and the adjustment made.

For integrity questions, describe the applicable rule, how concerns were raised and how confidentiality was protected. Do not disclose names or protected case details.

Expect follow-up questions

The official applicant guide notes that panels use probing questions. They may ask what happened next, what feedback was received, which part belonged to the candidate or how the result compares with another experience.

Memorizing a two-minute speech can make follow-ups difficult. Prepare the factual record around each example: dates, people involved, alternatives, measures, feedback and lessons.

If a detail is forgotten, say so plainly. Do not invent a number or claim authority that can be checked later.

Research the office and role

Read current official material from the hiring office, including its mandate, recent reports and the types of products named in the vacancy. This helps the candidate understand why a competency matters in that setting.

Do not turn the interview into a speech about the organization. Use the research to choose relevant examples and ask informed questions if the panel allows them.

Review the application submitted. The panel may ask about a screening answer, career move or result listed there. Dates and scope should be consistent.

Practical preparation

Practise aloud with a timer. The applicant guide says a competency-based interview typically lasts 30 to 60 minutes, though the invitation controls the actual format. Aim for answers that leave room for follow-up.

Test the video or telephone setup, keep the invitation and vacancy nearby and join early. Notes can contain short prompts if allowed; reading full answers usually weakens responsiveness.

After each practice answer, ask: Was the situation clear? Were the actions mine? Did I answer the named competency? Is the result supported? Those questions produce stronger preparation than polishing the same opening sentence.
