3M O2 Engineering interview questions

Interview was relatively smooth, I was contacted about a month after applying for the position. Reached out to by an O2 Program Manager for an initial, short phone screening. Set up an interview very shortly after later in the day, and near the end of the interview process he let me know that he was planning on giving me the position, and I'd hear back from HR soon. As a side note, very inflexible on their intern pay - you get what you get.
