UNDP Specialist interview questions

At the beginning of the process, things were well organized and quite reasonable. Technical tests and interviews were scheduled in advance and I could plan my time around it. After the interview, HR reached out with a request for references, providing 2 days deadline for completion. After this, the HR went quiet for over a month. I didn't get a rejection letter until I followed up, and the response was generic despite the amount of time spent on my side, it felt disrespectful of applicants. It is unlikely that I will apply for any positions in UNDP again.
