Payment Approved interview questions

Their interview process utilizes Slack where they will bring you into an interview and literally waste your time. They have been searching for the same position it looks like for over 6 months now, and I just think it's either a resume farm or they are just getting operational advice as they do their interviews. Not really sure if they even have a REAL job.One of the interviewers makes some interesting faces during the call while he asks questions. He's the guy that think he knows it all but knows the least probably in the entire company.
