Interview Preparation Tips
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.
