Texas Instruments Software Engineer interview questions

I had four technical reviews, two interviews by 2 different team leaders who asked about my technical experience and then asked general technical questions, technical "riddles". The third interview was conducted by the group manager who dived more deeply into my former employment background. The fourth interview was conducted by the division manager who again repeated many of the question that I were asked. I then was interviewed by someone from HR who tried to see what "kind" of person I was.
