They ghosted me deep into the process.
Had a great conversation with two people, did an assignment, had another great conversation. They seemed excited and said "you'll be hearing from us" but then they ghosted me. Attempts to contact them have been met with complete silence. They didn't say the process was over, they just went silent for months now, and are still silent. This practice is completely rude and exploitative, and personally I will never consider a position there again.
