I applied online. The process took 2 days. I interviewed at GGS Sachdeva Group of Educational Institutions (Kharar, Punjab) in May 2012
Interview
it was easy.
a few questions on your research topic, some questions on basic electronics and also there were some questions on communication technology. There will be panel of 2 to 3 people generally, asking questions of their own interest.If you know your basics well, there is not much to prepare for it.
