It was a 2 day hectic process. A 3 hr coding test followed by a technical interview on the same day. You will be shortlisted for the interview only if u get a 100 on 100 score in the coding test. The interviewers were very friendly and majorly evaluate you on your coding skills. The knowledge of OOPs concepts is a bonus. The shortlisted candidates were called for another round of interview at SRI Noida. I was asked questions related to software engineering which i could not answer being from electronics background.
