IBM Graduate Software Developer interview questions

I sent off my CV and detailed IBM-specific application form, and subsequently completed the IPAC test. I was then invited to an assessment centre at IBM Hursley. The assessment centre was composed of several group exercises, two solo interviews, a short presentation, and a programming aptitude test (similar to an IQ test, no previous programming experience required). I was told I passed the assessment centre next day, and that while this was not an offer of employment, or even a guarantee that IBM would like to continue with my application (this was made clear at the assessment day, should we pass it), that I was now in a pool of potential candidates. However, two months after the assessment centre (with no communication since) I was told that there were no positions available at this time, and that my application would not be considered any further. A very long waiting process for a very unsatisfactory result.

I filled their own unique application form (questionnaire) and sent the online application. A few days later I was invited for their online IPAT test. It was very tough, but then I received an email the next day that I have scored above the minimum score so now they will review my CV and application and will let me know whether I get promoted to the next stage or not. A few days later, I received an email saying I have cleared the CV clearance stage and now I am invited to the Assessment Centre Day. I was to send a confirmatory email regarding my attendance for the assessment centre day. Then they sent an email briefing the details about the assessment centre day and asking me to send the presentation file 7 days ahead the assessment centre day.
