Fairly brief interview for the position of entry level engineer .The first round was an aptitude test with a time of 60 minutes .There were some general aptitude questions and several technology specific questions ( Microprocessors,embedded system ,Software development life cycle, mobile phone technology related questions etc ) and the subsequent rounds were one technical round followed by a HR round. The technical round was with the lead engineer of the sub team they intended to hire us for ,so there were some very specific questions pertaining to the role we were offered.This round lasted for roughly an hour with questions ranging from basic c programs and microprocessors to some specific platform related questions. The round after this was with the senior manager in which there were mostly general questions about university study as well as general mobile phone technology related questions
