IBM Software Engineer interview questions

Started with a video behavioral interview - just asked about me, my background, etc. A few days later came video technical interview - string manipulation, data structures, basic programming in whatever language you choose (easy, but I would have failed without practicing on hacker rank first). About a week later was the on-site interview. Spent a few hours meeting with small groups of software engineers from the team. Again, totally non-technical, just asking about my background and skills, and answering my questions. I got offered the job on my drive home.
