I applied through college or university. The process took 1 day. I interviewed at Texas Instruments (Bengaluru) in Mar 2013
Interview
First round was 20 technical and 20 aptitude.
Technical mostly consisted RL,RC circuits.It also had Transformers,opamp and BJt based question..Apti was ok
A good amount of technical questions on OPAMP and dc-dc converters were asked. Do read on OPAMP in-depth and power electronics questions were easy and u will be able to solve if have ur switching basics clear.
