Selected to interview during a university career fair in Fall 2014. The first round interview consisted of behavioral and standard questions. Nothing unexpected, they'll ask questions to see in what area you would fit best based on your past experience and interests. Make sure to be as open minded and flexible with this, since jobs are highly competitive and give you a broader chance of obtaining a position. As always, know your resume and provide past results.
Was called for a second and final phone interview a couple of months later. The second interview begins with behavioral questions such as "Tell me about yourself," "A time when you were in a team/leadership experience," and "A time you had an opinion and your peers disagreed." The interview then transitions into technical questions. Know basic terms within your area of study. I was asked about how I calculated and analyzed data from past internship experiences. Again, just know your resume and how you obtained any results. These questions will probably vary for each interviewee since everyone has different experiences. No out-of-the-blue questions, all technical questions were related to my past experiences listed on my resume.
However, nearing the end of the interview, they did provide a short and easy business case situation related to supply chain. Nothing you had to calculate or solve, but more of a "what information would I need to make a decision" type of case. If you hate math or case questions, don't fret, you'll do just fine by having basic knowledge of your major (Tip: A review to freshen what you have learned will do miracles for this).
Overall, a really good interviewing experience. Interviewers really listen and take your interests into consideration. Best advice is to know your resume, be flexible, and comfortable. Good luck!
