Event Career at the United Nations

I have always wanted to work at the United Nations. I had the opportunity to attend this CUNY student event that discussed opportunities to work at the United Nations.
I can say that it was very informative. Above all, how to send the resume and the cover letter and the different titles that exist within the United Nations.
The key points of this meeting:
• Information and advice to apply for jobs and internships at the united nations
•  Websites
•  Types of personnel and personnel
•  Work experience requirements by professional level and higher categories
•  “Carl” model for answering competency-based interview questions
•  Work experience requirements per level in the professional and higher categories
Here is the Information link of the Career Event Brochure.
which can be very useful if someone wants to work or do an internship at the United Nations.
