There were 3 rounds round 1:(aptitude and letter writing) :i was exempted from the aptitude , i only had letter writing exam,it was a basic letter to ask for permission for organizing a get together at the work place. round 2 : (Technical +managerial) : i was first told to introduce myself and then they started asking questions related to the hobbies i had mentioned. Then they started with the techincal part of the interview,i am an electronics engineer therefore i was asked questions varying from the basics of EDC like recognizing the components like resistor, transistors, mosfet etc, to wireless networks basics like gsm cdma .I was asked about integrated circuits like ic 555,difference in 8085 and 8086 microprocessors etc. After grilling me with techincal stuff for 45 minutes, began my managerial round where i was given situation oriented questions . round 3:(HR): it was 2 on1 round for me, i was again made to introduce myself ,this time they asked about my family background as well . the questions were very basic and both the interviewers were very nice during the whole process. It lasted almost 15 minutes where i was asked questions about my educations ,strengths etc
