Texas Instruments Testing Engineer interview questions

It was a six person, panel interview with basic questions about your resume. They basically wanted to see what kind of a person you were. Then, they ended with a three question, 10 minute session where you had to answer these questions from a small board on your own sheet of paper, while they all stared at you. At the end of this process, you explained your work and answers with the panel. The questions asked were: 1) Find the equivalent resistance of a circuit. 2) Solve a simple op amp circuit to give the output, relative to the resistors. 3) Show what a transistor circuit example did. After this interview, free lunch was provided, a cheesy video was watched, and a brief description of the job/jobs were given to everyone interviewing, while the chance was had to meet a few people and ask about the job.
