I had 4 interviews for 2 different jobs. I got one of them. Everyone was SUPER nice. I bugged out about having a presentation ready to show but it was purely based on personality fit. For me, it was a test of displaying soft skills and they would teach me hard skills later. They all asked me the very same standard questions and I was totally honest about the good, bad, and ugly of my career. ***You need an invitation from an existing IBMer to get the job in my experience.
