Important aspects of the process include:

• Applications remain active in the talent pool for six months.
• UNESCO managers review applications when relevant internship opportunities arise.
• Selected candidates are contacted directly by hiring managers.
• If applicants do not receive a response within six months, the application is considered unsuccessful.

Due to the high number of applicants, UNESCO does not respond individually to every candidate.

Important Application Tips

Applicants should keep the following points in mind when submitting their application:

• The application process must be completed within one hour.
• Ensure that your contact details remain valid for the next six months.
• Applications must be submitted in English or French only.
