Applying to NGOs, UN agencies and research centres

Understand grades before you apply

UN agencies advertise by grade (G for general service, NO for national officers, P for international professionals). NO-A and NO-B suit early-career nationals; P-2 and P-3 need several years and usually a master's degree. International NGOs use their own bands but the pattern is the same: an "Officer" role, a "Specialist" or "Manager", then "Advisor" or "Lead". Applying two levels up wastes everyone's time; one level up is normal.

The cover letter answers three questions

1. Why this organisation and this role, in one specific sentence that shows you read the posting.
2. The two or three requirements you meet best, with the evidence, in the posting's own order.
3. What you know you do not yet have, and how you would close it. Honesty here is remembered.

Keep it to one page. Address the requirements list directly; hiring panels score against it.

Competency frameworks are literal

Many organisations score on named competencies (for example "Delivering results", "Working with others"). Your examples should be labelled with them. Use one paragraph per competency: the situation, what you did, what happened.

Consultancies are a different game

A consultancy call wants a short technical proposal: your understanding of the task, the method, a timeline, a daily rate, and past assignments that resemble it. Eligibility often requires a registered entity or a team; check that before writing.

Referees and portfolios

Line up three referees who have seen your work and warn them each time you apply. For data and geospatial roles, a public portfolio (a GitHub repository, a dashboard, a map, a short report) does more than any adjective in the CV. Link it.
