Human Rights Watch Associate interview questions

The interviewers were nice, the lack of communication was extremely frustrating. I had a basic phone interview to tell me about the position then moved to the final panel interview the week after. They gave me a lot of false hope by saying that I "stood out the most of all candidates" and am "so well spoken and passionate" and how the "organization would love to have me" and am "a great fit for us" and how they are lucky to have found me. The job was set to start 2 weeks after, and only after a month of no contact did I receive a rejection letter. They even told me they will keep me in mind for future roles and I emailed them twice for follow ups and questions and did not get any response back either. I interviewed for a similar role a few months after and was once again not alerted for a month regarding my status.
