Addy I have been on weird interviews. One time I waited an hour and the contact never showed up or rescheduled. Another time it was an interview to participate in a pyramid scheme. Once I went for an interview that doubled as job training and it lasted 40 hours a week, with unsuitable applicants culled out daily. Still I would have loved to get a job offer on 2 out of 3 of the jobs. If you like the job itself I hope you get it.
