All I had to do to get the interview was talk to a few people at my school's career fair. If you have solid credentials (work experience in open source, good GPA, etc.) then you have a good shot at an interview. They do a lot of Python programming and working with open source technologies in this sector of IBM, so experience in that world is also a plus. The interview was not technical, although they were prepared to make me an offer based on the way that I described my experiences with the various technologies that they were interested in.
