Interview Preparation Tips
Round: Case Study Interview
Experience: No one would be eliminated in this round. They will provide you ample time - around 40-50 minutes to write a response on a case study. The topic would be new and unheard of, but you can think and write peacefully in that amount of time.
Tips: Make sure you highlight the points made and do remember them for the Group Discussion phase.
Round: Group Discussion
Experience: One-third of the guys will get selected for the interviews from each group of 8-10 guys. The topic of the GD would be same as the case study. Now, its time for you to recall the points you made during the writing section. The GD will last for around 15-20 minutes.
Tips: Good communication skills, relaxed but expressive tone. Don’t be silent and try to speak up whenever you get a chance. Try to bring new air into the discussion and think from all the different perspectives. You should speak at least 2-3 times, even if you just say 1-2 sentences each time. That will do. They also individually ask each person to speak, specifically those who could not speak, but you had better not be that guy or girl. There is no need to fight for summarizing the GD. Try to show that you are involved throughout the GD.
Round: HR Interview
Experience: There will be two guys, one from technical and the other HR. They both ask questions at the same time and they discuss among each other as well. They mostly try to detect any fraud or fake thing you did in your project or intern. All the technical questions come from your CV. So, your fate is kind of in your hands only.
Tips: Prepare hard for Projects, Internships etc. Don’t panic. They try to see how you react in a pressure situation and actually behave as if you are not impressing them. Just be calm and keep on speaking. If there is something you want to say and they interrupt you, its better you ask them to give you a chance to explain it in details. Do have a few questions in mind to ask them about your job profile and Wipro. That is the final nail in the coffin.
Skill Tips: A minimum CGPA of 8.0 was mentioned and later they relaxed it to 7.9. They were giving quite some importance to the Internships and Projects undertaken and were trying to judge if you actually did something new and genuine. They were dwelling deep into it. As I said, prepare well for them just like you prepare for BTech Project Viva. They do ask a lot of questions.HR questions should be prepared thoroughly. A background check of Wipro and IT sector companies is a must. Prepare well for group discussions. Try to get background information about the IT sector and the company. Prepare your CV thoroughly.
