ALSTOM interview questions

I applied through a staffing agency. After screening for the job role, a virtual interview was scheduled. Trust me, it was an awkward interview for me. The panel has 4 guys including one senior member. He is eating something and asking questions. That was very unprofessional in a video call that too in interview calls. They do not have respect for the interview candidate so I did the same. The questions are easy but one of the panel members does not know Aluminum is used for forging :-) I did not hear from them. If I get the call, I would like to give them feedback about their interview. I have mutual friends who are working in this company. It has a bad reputation and culture like the below service based. So beware of this company.
