IBM Consulting interview questions

Overall a very quick and painless process. Mine were conducted online through webcam. Consisted of 3 interviews, all 30 minutes long (to the dot, with 15 minute breaks in between). 2 behavioral and 1 case. Everyone was very pleasant, were conversational with your answers, and seemed enthusiastic about their jobs. The behavioral interviews were split between one assessing your team experience, the other about your problem-solving/intellectual capabilities. The case was very simple, involved implementing a technology. Very basic math, and then simple questions such as steps to implement, risks/issues to consider, etc. While the process was easy, it was hard to assess what they were really looking for. The questions kind of overlapped and didn't really assess other important traits you should have on the job, just teamwork and working on projects. I haven't heard back yet, but I feel like since the questions were simple, how do you really differentiate yourself? I see some people here saying that they wanted to see enthusiasm about IBM, but they didn't ask me a single thing about why I'm interested in IBM or the program. I guess a lot of it is personality.
