Human Rights Watch interview questions

Took about two months after I initially applied (emailed my resume, cover letter, etc.) for them to contact me. Set up an online video interview with 6 questions (why I want to work with HRW, specific questions about the job). Got an email about 4 days later saying I passed the video interview and wanted to set up an hour and 15 minute written exam with me. I had to write a letter to a senior official, write an email in French, and proofread a HRW report and then format it. Never heard back after that, even after two follow up emails. Personally, I felt kind of weird about the organization as a whole after that experience. I understand that it's a big organization and everyone is probably really busy, but when someone takes the time to interview with you and go through an hour and 15 minute written test, I feel like the least you could do is respond back to their email and tell them they didn't get the job? Kind of turned me off to HRW to be honest.
