Yes, why not! Recent trends show that an increasing number of people are getting interested in working in the development sector, and even International NGOs are also offering great opportunities for potential people.
But, before you apply anywhere, introspect. Write about what you feel about yourself in terms of your career and other priorities. If you are willing to learn and grow in this sector, are flexible and keen to understand the limits of a career in the development sector, then you are good to go.
Always remember, NGOs look for professional and managerial skills, apart from many other technical skills. Bringing a different professional skill to the table will be helpful, and would result in a win-win situation.
If you are looking to kickstart your career in an international NGO, give this VIDEO a watch.
