Blue Door interview questions

They ghosted me after interviewing with them for more than five weeks! I completed a phone screening and then had to answer five questions via email about my background in fundraising. I completed two interviews and had to do extra “interview work” during the second interview. I never received a rejection email even though I followed up after each interview. I found out a few days later that they had reposted for the position. A quick rejection email would have sufficed but instead there was just radio silence.
