The United Nations Development Programme (UNDP) does not have a specific age limit for recruitment. However, all candidates must meet the minimum education and work experience requirements for the position they are applying for. Additionally, UNDP has a policy of non-discrimination and seeks to promote diversity and inclusion in its workforce, which includes individuals of all ages. It is worth noting, however, that some UNDP positions may require a certain level of physical fitness or other specific qualifications that could potentially limit the pool of eligible candidates based on age.
