SIPCO interview questions

Applied through Linkedin. 2 months later received online test and passed it. Scheduled an interview. The interview was very unprofessional. The talent manager kept laughing during the interview and making fun of my answers. But I tried to keep calm and cooperative till figured out they are not offering the position in the field that I'm interested in so I told them that I'm not interested in the position they are offering. I wasted my time, they should've mentioned the areas they need in their graduate program. And their Tahlia factory is very old and needs to be rebuilt.
