Round: Test
Experience: It was 2.5 hour long AMCAT test comprising of Quant, Verbal ability, analytic ability, technical section comprising questions from C, DSA and other computer fundamentals.
The test is not that difficult so the cutoff generally goes high
Duration: 150 minutes

Round: Technical Interview
Experience: Started with a formal "Tell me about yourself". While I continued for 2 minutes, he read my CV word to word. Since I had always been interested in programming and so it was my strong point. But he didn't even ask my area of interest and directly asked me question from core electronics that too application based. The questions were like this:
1. "Suppose you are recruited as an ECE engineer in IRCTC. Your job is to stop the train accidents that happen every now and then. Use your Applied Electronics to construct a scheme/plan. Tell me how will you proceed?"
I was literally stunned at such a question. However I took some seconds to think and gave him 2-3 answers all applying the idea in one way or the other. Like use of modern sensors, RADAR technology, Use of automated baricates at crossings and explained it to him. He wasn't fully convinced but somehow I was able to do OK.
After that i told him that I was more comfortable in programming and computer science subjects. he neglected this altogether and kept asking me ECE questions. Next questions were like "Explain the working of IC 555 timer." I told him straight away that I didn't know it very well.
After this he moved on to ask me the difference between GSM and CDMA technology, how mobile phones work and the whole concept of cellular telephony. I had prepared well for it and told him even more than he was expecting so he was quite pleased to hear it.
Next were some questions from computer networks like how internet works, Network model etc. I told him I was studying CN currently so i gave him the basics of OSI model explaining briefly each of the 7 layers. Also told him about sub-nets, sub-net masks etc.
After this he asked me some general question from my CV about my achievements like KVPY scholarship, NTSE scholarship and about my research paper. I explained it to him to the best I could. Then I asked a couple questions from my side and this interview was over. The whole process took around 35-40 minutes.
Tips: For technical, have a solid command over all the fundamentals of important subjects. You need to start early. 3rd year is a good time to plan and start your preparation. In your summer holidays before 7th semester, don't focus your full attention on your training. It is also important but you need to take out some extra time for aptitude building, revising concepts and enhancing your communication skills. Be confident and be honest. Try to make the conversation as interesting as possible. Try to be more interested in the company. If possible, do a little homework about the company visiting your college. It will prove to be useful and certainly will give you an edge above others.

Round: HR Interview
Experience: It had hardly been 15 minutes after the completion of my technical interview and I was called for the HR round. Again it started with “tell me about yourself” but this time the lady asked me everything about my family, my schooling, my interests and all. It was a really good 30 minutes spent as the conversation was really interesting. Then she asked me whether I had any problems in relocation. Then it led to a good discussion about how is life different in Hyderabad and Chennai. I asked her a little bit about her education and how she started a formal career in management. She was very happy to respond. Lastly, there were some concluding remarks, a formal thank you and the interview was over.
Tips: Make the interview as interactive as possible. Ask a lot of questions. The person should know that you are really interested in the company. Prepare good answers for HR round well in advance.Any extracurricular activities that you have been a part of may come up in the HR/Managerial round. I was asked what have you done in your college life so far other than studies. I had a lot to say in that matter as i was involved in dramatics, debating, quizzing and other activities right from the school level. They may be interested to know how efficiently have you handled any complex or challenging situations in your life. I was the Event Executive of Fashion Show "PANACHE" in BLITZSCHLAG'13. I explained to HR what all I did to make that event a success and she was really impressed with it.

General Tips: CGPA matters. Not always but definitely it's a point worth considering when the interviewers are confused even after the completion of all the rounds about which students to select.Although not specific to this company, but other companies give a lot of credit to CGPA. It is an important factor along with the 1st written round for the shortlisting of candidates.So, maintain as good a CGPA as you can.In your technical interview you are going to be asked about at least one project that you have been involved in your college life. If some project is mentioned in your CV, it is certain that the interviewer will ask you about it. I have seen discussions as long as 1 hour or more on one's project itself.
