I applied through university. The process took 1 day. I interviewed at Texas Instruments in Aug 2013
Interview
They take a two hour online test which included questions on analog electronics and digital electronics concepts. People were shortlisted on basis of their score in this test, After that it's your response to similar questions in the interview which matters. Computer architecture and vhdl concepts should be clear. Questions depend on the type of skills their project demands.
Online Assessment followed by 2 rounds of technical interviews. Online Assessment consisted of 3 parts - Analog, Digital and Aptitude. Analog part mostly consisted of questions from RC circuits, Opamps, MOS Circuits, Oscillators.
I interviewed at Texas Instruments (Bangalore Rural)
Interview
I am only having only one round of interview
Where they asked mostly about rc circuits. Op amp basics and mosfet questions.
The interview almost happened for 1 hour and it is a good experience
Keep your basics clear and intuition well prepared. Knowledge in RC and small signal is must. Himangshu Agarwal and Chembiyan T must and basics of opamp etc. Input and output impedance calculations etc.
