Texas Instruments Intern interview questions

I applied through my university .The process was spread over 2 days. The first round was the online test , which consisted of basic questions . The test had 3 sections , analog , digital and mental aptitude. The second round was the pi , this round was the real filter and they looked for people with very strong basics. After this there was a hr round which was merely a formality.

Questions from fundamental concepts of analog and digital electronics, based on my resume. They also asked to explain all my projects and courses that I had done during my course of BTech degree.
