Schneider Electric Project Manager interview questions

Two telephonic interviews some technical, some project management. Went well so management asked for personal interview. Personal Interview: Nobody informed how the exact process was going to work. Total 5 people came one by one to take interview and it was not until my first interview was over that I got to know the actual process when I asked specifically. After first person/round second guy comes in and asks how to resolve issues that they're facing currently with just a brief description. I thought it was absurd. Third person comes in who isn't even aware what position is and what is the job description. He asks some random questions and leaves. Fourth person conducts interview like he's taking an interview of a fresher. Finally last person who's head of the division and questions the experience. Commenting why didn't you earn experience in the field other than the one I'm working in. When asked about the job description he too is not aware. It was totally waste of time and money to attend the interview. Management need to take a look at resume before calling for an in-person interview.
