Foreseeson Technology interview questions

Had a screening call and follow up interview. Second interview has 3 people on it, however one didnt actually show up just joined and muted with no video. They didn't seem to be collaborative in the call and one person asked one questions and said that's all from me, the others then laughed and said this is just the beginning. I then got zero follow up which after being screened and a panel call would to be me standard.

It was amaizing. I recived the offer. They present me their company with presentation. We discus about my responsibilities, my work experience, studies and we speak around 2 hours with project manager ang general manager
