IBM Software Engineer interview questions

I had regular online cognitive testing, and then after some time was asked in for the first interview. This was a soft skills interview, where I was asked about my career prospects, my experience and my extra curricular activities. I was also asked to talk about a recent invention I found interesting. It was very basic and took about twenty minutes. The second interview was on the floor I'd be working. It was a great space, with awesome over looking views and shared tables so you weren't stuck in your own cubicle. Two people interviewed me this time. They asked me most in depth questions about the programming languages I knew, different projects I completed and they also brought in a Rubik's cube for me to demonstrate that I could, in fact, solve it (this was on my resume as a little joke). They were very friendly and allowed the interview to become quite conversational.
