I went through two rounds of the video interviews which I actually thought was cool because I have never done an interview like this before. What is annoying is taking the time to do these video only to be ghosted. Just lets you know this is not a organization that values peoples time. I am sure they have a lot of applicants but the least you can do is send a message saying yes or no especially since they are asking you to take so much time to complete these video interviews.
