How many questions are asked in a UN competency-based interview?

Typically between five and twelve, depending on the number of competencies in the vacancy announcement, plus probing follow-ups within each question.

Are technical questions asked too?

Yes. Functional or technical competencies are assessed alongside behavioural ones, sometimes through a written assessment before the panel interview.

Do panels ask about gender and diversity?

Increasingly, yes. Respect for diversity questions covering gender, harassment and multicultural working are common even when the vacancy does not list them explicitly.

Behavioural interviews at international organizations

How competency-based behavioural interviews work at international organizations: panel composition, scoring grids, question design and how to prepare systematically.

A behavioural interview assumes that past behaviour predicts future behaviour. Instead of asking what you would do, the panel asks what you did — then rates the evidence against a fixed competency framework.

Who is on the panel

Most international organization panels have three members: the hiring manager, a human resources representative and a subject-matter or gender/diversity focal point. Each scores independently before the panel converges on a consensus rating.

How questions are designed

Questions are derived directly from the vacancy announcement. Every listed competency must be probed at least once, which is why announcements that list five competencies usually generate ten to twelve questions, plus probing follow-ups.

How answers are scored

Panelists record evidence and match it to positive and negative behavioural indicators. Answers with no concrete action, no personal ownership or no result collect negative indicators even when the story is impressive.

Probing questions

Expect follow-ups: "What exactly did you do?", "Who disagreed and how did you handle it?", "What would you do differently?". These exist to separate rehearsed narratives from genuine experience, so know the detail of your own examples.

How to prepare

Extract every competency from the vacancy announcement.
Read the official positive and negative indicators for each one.
Build six to eight STAR stories that between them cover all competencies.
Rehearse aloud, timed, and record yourself.
Get scored feedback and iterate on the weakest competency.
