3M Internship interview questions

When I was interviewed for a marketing internship position for one of the divisions, it was my supervisor who directly contacted me. I just sent an email of intent with my resume attached and she replied to me with an invitation for an interview in their office.

Three students were for the interview. One person was interviewed alone while the other two were interviewed at the same time. Most of the time, the interviewers asked the same questions to the two interviewees. There were times where they did not let one of the interviewees to answer the same question. The interviewers did not even introduce themselves at the start of the interview. Also, one of the interviewers kept interrupting while the interviewee was talking. Lastly, one of the interviewers also made some facial expressions which seemed as if she was not interested/listening.
