The interview began with MCQs complete based on concepts explained Ashok Pathak Advanced C book(green color). Second round was moderately easy with few questions on C, device drivers and OS. Last round was typical based on behavioural basis where intentionally questions were asked mostly on CPP of high difficulty level, and the interviewer was stubborn/rude. Although I cleared the round and last round was just HR, I declined to go further since I got offer from Mitsubishi Electric.
