Campus placement is the prime source, they also give requirements on job portal also. Interview process is directly with technical person at company location and then with HR/ Admin people. simple as it is.

The interviewing and the offer takes months to process for this firm. I was interviewed in May and got an offer in November. The interview involved at panel of 3 foreigners and one HR. There was discussion about what I studied and what I did in my engineering but somehow all them dodged the question when asked about my job profile and the kind of work I would be doing.
