Interview Preparation Tips

Round: Interview
Experience: Its not an elimination round, you can go with your informal clothes on. Any one who has prepared for day 1 and day2 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.
Tips: 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: Interview
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-academics 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.

Interview Preparation Tips

Round: Test
Experience: My first Interview was for the post of Network Engineer in HCL Technologies held in April 21, 2009. In the morning in that day at 9.00 AM I am with dressed up with formal dress code, black shoes and a tie. I waited there for around 2 hours for the company officials to come. They came at around 11 AM. Then they started giving information about HCL Infosystems through a powerpoint presentation and what all procedure they are going to follow in their recruitment process.
The recruitment process consisted of two sections:
1. Aptitude Test
2. Personal Interview.
The Aptitude test consisted of 30 questions in Quantitative Aptitude and 30 questions in Non Verbal Reasoning and the time allotted to complete the test is 60 minutes. The questions were quite tough and challenging. It was evident that the HR were expecting more talents for their company. I could answer about 40 questions and there were no negative marks so I answered all the questions. I was quite confident that the cutoff would be less that 40. We waited for the results of Aptitude Test. The result came around 2.30 PM. About 45 candidates were selected for the personal interview and I am glad that I am one of them. From the results we could guess that the cutoff was 35. The Personal Interview was at 2 PM after lunch. At 2 PM we waited there for Personal interviewer. Four different panels were there for conducting the interview. My turn came at evening 5 PM.

Round: HR Interview
Experience: HR: Are you Anbarasan?
Me: Yes Sir.
HR: Take your seat.
Me: Thank You Sir.
HR: Introduce Yourself Anbarasan.
Me: (I gave a brief Introduction about myself)
HR: What is your father?
me: He is a Civil Engineer Sir.
HR: Why didnt you join civil branch in engineering
me: I am more interested in Computers than civil Sir.
HR: What is your mother?
me: She is a housewife Sir.
HR: What is your career Objective!
me: My career objective is to work in a challenging environment where I could
constantly upgrade my knowledge thereby contributing for the organisation where 
I work and my professional growth as well. And my life ambition is to become a 
reputed Ethical Hacker.
HR: Good. Who is your role model?
me: Bill Gates Sir. Because he is the best programmer in the world. I like his thoughts more than his programming. He became the best businessman in the world because of his great thinking. He is a really innovative and inspiring personnel.
(Then He asked questions from all topics in Networking . As I am good in Networking I could answer his questions. I could see that he is satisfied with my answers.)
HR: How did you learn Ethical Hacking?
me: I learned through lectures of Ankit Fadia Sir. But still I need to learn more in Ethical Hacking.
HR: Will you join HCL if you were placed anywhere?
me: Sure Sir. When it is HCL, I wont hesitate sir.
HR: Your Personal Interview session ends here. You can leave and wait for the results
me: Thank you, Sir. 
That interview session took 30 minutes to complete. And the result came at 6.30 PM. Out of 45 students, 30 got placed. I was also got selected in the interview. Almost all of friends got selected. I was glad that I got the Network Engineer Job. That was the most happiest moment I ever had.
