Interview Preparation Tips
Experience: There was only one written round after ppt presentation. It was pure technical based paper consisting of c, java, datastucture, network and operating system.
There were around 60 questions to be done in one hour. All questions were easy but conceptual and little bit tricky.
1. In C.
Most of the questions were based on bits manipulation and string and union. 2. In Data structure.
Questions on tree , heap, red black tree and balanced tree and complexity. 3. In Operating System
It was really conceptual. Most of the questions were on virtual memory concept and scheduling and semaphore. 4. Network
Questions on layers and their protocols. Numerical that needed transmission ,propagation and bandwidth formula. Some general conceptual question including switch, hub and gateway.I attempted every section since sectional cutoff was there. I didn’t attempt any question that I was not sure for, since there was negative marking. I also didn’t attempt any numerical.
So, attempt each section such that you can clear cut off. No need to attempt all questions of each section.
Round: Technical Interview
Experience: After written test , only 4 from Mca and 4 from Mtech were selected for next round.
It was also pure technical round.
Interview started just after result was declared. Since there was only two panels, It was taking time.

Experience: 2 rounds of technical interviews were there. Technical rounds started with basic questions and moved on till programming. They covered all the subjects such as OS,CN, DBMS,C, C++, Data Structures.
Round: HR Interview
Experience: One HR round was there.
General Tips: My journey for placements started with attending my first interview at Oracle (in Aug). Different companies focus on different subject in your interviews. While some of them stress on your coding part, others might be interested only on your project. I have seen few of my friends, were only project was asked in depth for 1hr, and they were also asked to write few code lines of your project.Famous puzzles were common in many of my interviews, while few new questions were also heard. Be strong in coding, and confidence is all that matters."Confuse or convince", I would say!
Skill Tips: Be confident. Do not neglect practicing aptitude problems. They look to be simple and everyone can solve it, but speed matters when you are writing your written test. Try to know at least basic info about the company before attending your interview. Practice the famous puzzles/quiz problems and also your role in your major project.
