I was interning for another position at TI, in which I had also interviewed for, but had interest in the Applications Rotation. I applied internally and got an in-person interview a few weeks later. The interview consisted of two, two person interviews, both of which had a few behavioral questions. The first interview focused on opamp questions and some circuit analysis. The second interview asked a few C/programming question since that is what I said I knew. Overall, the interviewers were non-threatening, and it felt like they were genuinely having a conversation with you.
