IBM Software Developer interview questions

I applied through University career fair and got a call from the hiring manager after about 3 months. They said they were interested in discussing an intern position and gave me the details. The first round was a technical and social interview with the hiring manager and the project manager and the senior tech architect of the branch. Questions were on databases, my previous projects, few more technical questions to be solved (a little complex towards the end). I was then given a programming project to be done at home and submit the code along with description. I was interviewed on the project and few more technical questions by the hiring manager and then the third round was behavioral and social. They asked me to take an aptitude test which is a must for all their employees and was extended an offer.
