UNHCR interview questions

The process took over 3 months. I interviewed at UNHCR in Nairobi in October 2019. I received invitation for interview a month after the application deadline. The interview was via Teleconference and there were 4 people on the panel: Resettlement officer, hr officer, hr associate and head of sub-office. The interview took only 30 minutes. There were 5 questions, competency-based. "Tell us about a time in your previous job when you did..... ". I did not hear anything from them about the results of that interview for almost 2 and a half months. Then I got an email saying that the job position had been cancelled.
