College Name: IIT KHARAGPUR

Round: Case Study Interview
Experience: Its not an elimination round, you can go with your informal clothes on.
Tips: Any one who has prepared for day 1 and day 2 companies will get through this round. Just read news papers and learn to shoot graphs here and there even if it has got absolutely no facts and definitely practice to write a lot. Be prepared with both for and against the topic coz the interviewer keeps changing the topic in between the GD.The topic was same as that of the case study Don’t write bullet-ed points, this makes your cases look small. Try applying your vocabulary spectrum. Try to give exhibits even if you don’t know any facts.

Round: Group Discussion
Experience: 12 students on the table, one interviewer.
Tips: Play old school .But don’t wait for your chance, just break into it, but with a gentlemanly attitude. Try giving examples. Throw arbitrary facts to prove your points, if you don’t remember the real figures.

Round: HR Interview
Experience: Two interviewee were present.
Tips: Don’t start with your brilliancein your core subject. Tell them you hate your department. Convince them that you won’t ditch them for a Ph.D or an MBA. Tell them you have a friend at Wipro who keeps giving you intel about how great the company is. Look confident and if at times you can be funny, they will appreciate it!!

Skill Tips: 8 and above CGPA is required. Later it was lowered to 7.9, mine was 7.98. They mainly ask HR questions, so being involved in Extra-academic activities gives you more that you can talk of. I had an eye for coding in C++. Helped me on this, but my extra-acads list was enough. Coding was just a bonus. If they are non core its better. But my both the internships were core based. You just have to convince them why you are dropping from core.

Round: Interview
Experience: 1st round: Panel of two. Asked questions about the projects which were mentioned in the resume. A few questions were asked about the core intern which I did. Asked about the family background.10 got selected in the next round of interviews.
I think for the second round of interviews they selected on basis of CG.

I did well in the interview and they liked my story about my projects.

(Dennis got a call and he typed in some thing in his laptop. I knew it was from sam)
Interviewer: Ok kiran please wait out side will get back to you in a few min.
Me: I said yes and walked out of the room and was little anxious but the people who were waiting outside wanted to inquire why it has taken a lot of time.
After some time Dennis along with Sam came up to the lounge area and called me and spoke to me saying that they were satisfied with my interview and told that they were checking my accent and my technical knowledge and told me that I was selected for this round and need to attend a written technical test and also if I clear there will be a HR round and if cleared will get the appointment letter. Then they handed over a sealed envelop and told me to give to the HR
I was a bit relaxed now and was waiting to go for the next round people around me congratulated. After few min a interview board member accompanied us in the Cab to another facility a few hundred meter away from this facility.

Me: I said good Afternoon

After some time the HR came.
HR: Congrats you cleared the written test 
Me: Thanks 
HR: So you are a defense person and where are you working?
Me: Yes, I am working in Air Force Station Delhi.
HR: So you want to join a pvt organization from a govt organization, don’t you feel that you are loosing security of job?Me: Yes, I want to join a corporate sector since it was a dream for me and I think the circumstance have paved the way for me since I am also not interested to be in Air Force because I am away from my family and also this posting makes it very difficult for me to be with my family and it will be for five years. Secondly I don’t feel any that I am loosing Job security since any how I have to retire after 20 years of service and I have finished 12 years and I cannot justify to my duty if I am not interested. So owing to moral grounds I want to join a pvt organization.
HR: So you think that your family comes first than your job?
Me: It depends on how a person thinks but for me both are important because without money I cannot survive and without a job I cannot earn so I balance both Job and Family and prioritize them.
HR: What is the remuneration you are expecting from us?
ME: I am expecting a good remuneration from you but I would be happy if I am paid as per your organizations standards so that I might not feel that I am left out in comparison with my colleagues. 
HR: Are you willing to work in any shift?
Me: That would not be a problem for me because I have been doing duties in Air Force on the call and 24/7. So I do not have any problems
HR: Ok you may go..Me: I thanked her and walked out of the room.
After an hour the HR came and gave me all the details and told that I got Selected!!!
This gave me the confidence that I can do well in the future.
Though I did not join the Job it was a very good experience for me and it helped me in an interview which I attended in Bangalore in an IT company and which I have joined as a Quality Assurance Lead.
