3M Lab Technician interview questions

They invited me to interview and a group of people interviewed me. It was a complete waste of my time. Most of the people interviewing me seem disinterested. I don't know if they were burnt out from interviewing so many people or what their problem was. One guy was more worried about texting on his phone about a lunch date he was going to have later than in the interview. It was extremely disrespectful and I almost walked out mid interview. This company seems like it's full of bureaucratic scumbags and brown nosers. I will never waste my time so much as giving this company the time of day again. It's an older crowd so I think they don't want to get younger talent in who can take their place or some sort of simple minded mentality like that.
