Texas Instruments Analog Designer interview questions

Met a recruiter from Texas Instruments at my college career fair - they were extensively looking for analog design interns. I had a decent coursework with 2 relevant projects and no work experience.

The interview was for an internship during summers-2012 in Texas Instruments, Bangalore. There was a written test first comprising of questions from subjects like Signals & Systems, Circuit Theory, Control Theory, Probability & Analog Electronics. Those who qualified were selected for the technical interview. The interview comprised of more technical questions from the same subjects as before, only this time it was very conceptual & involved questions which though could be answered orally without making any calculations, but needed decent understanding of the subject. They were a bit confusing as well & there was considerable chance of making errors too, errors which you normally wouldn't have made.
