Round: Technical Interview
Experience: there were two technical panelists. they first asked me to explain what was my internship. since I did my internship in a steel plant they asked me to explain the product flow. they also asked me to write zones of blast furnace and function of steel melting shop. then they asked me to the above questions. mostly on material science and manufacturing engineering.
one of the panelists showed me a pen and asked how would you harden the surface of the pen? So I asked him as a designer I would need to know the loads being applied on the pen. He wanted the exact answer and was impressed. he then asked me questions on power plant engineering. I had not studied any course on it so I told them that I know only basics. so they asked me to draw a block layout.

Round: Group Discussion
Experience: Manufacturing sector in India is ailing (India needs alignment in Manufacturing Sector). We had a healthy discussion.
Duration: 10 minutes

Round: Technical Interview
Experience: Interviewer was much more focused than I was. He asked me, what is your favorite subject? I listed 3-4 subjects but sensing his eagerness to ask questions, I stepped and added on which project I am currently working. He took few seconds to understand my project and then asked all the questions related to my project only. Things went on smooth after that because ball was in my court. With 5-6 questions like scope of project in real situation and where this system is currently being used (answer was - in their own company) and some water flow pressure directions in solids, he left me.



Tips: Key for Technical Interview is at least prepare your one subject so strong that it can give you a chance to survive interviews. Be calm and composed, don't hurry up the things, try to drive the interview in your zone only (play on your strengths).

Round: HR Interview
Experience: Interviewer was more obsessed to his brand new IPhone and implicating agreements in very unusual manner. He asked me to introduce myself, interfered me in between and asked another question regarding my views on India-Pakistan Relationship, I tried to be brief as much as possible, trying to cover every aspect in relationship both positive and negative part. He stopped me in between and said thanks! Of course I was not expecting a very very short HR interview but it happened. And that is what whole process is, a chain of unexpected events.

Tips: Key for HR Interview is try to improve your communication skills, it matters and in the end a lot. Do more activities and make yourself much more than 1 page resume. Make a character for yourself and try to stick to it.
