World Health Organization interview questions

After the CV and a test round (making a PPT about the topic). The HR lady was really friendly and encouraging. I didn't expect to present the PPT we made more than 1 month ago and so I went completely blank, but she was trying to ask questions to help me brainstorm. The interview was conducted quite a long time ago, so I didn't remember exactly the set of questions, but there were questions about yourself, why did u choose WHO, your strengths, weaknesses,.. Later she asked several questions about my availability,.. etc

Competency based interview. It was a video call with a panel of four and there was a four or five questions. Questions were competency based, which means you were supposed to give good examples from your previous work experiences.
