Straightforward and behavioral. Asked me three questions. Always use STAR (Situation Task Action Result) to clearly explain the problem and how to you solved it. While I don't really remember what was being asked exactly, I will say that I remembered to look at my resume, write down some of the problems I encountered during those activities and engineering projects that I solved over my undergrad and post grad years. Most likely there will be a diversity question, or they will expect some kind of an answer that has diversity in it. Whatever it is, be truthful, outline your thoughts, match it to the job requirements and Boeing mission statement, do some thorough research before you go in to the interview. Make sure to ask questions.
