GROUP DISCUSSION CSC is mainly looking in your communication and how well you are confident at. These guys are giving chance to everyone in putting their own points. i.e., they are conducting it in orderly fashion. She gave us: Should sex education be included in academic of school children. I was the first to start the GD, so, I went with the topic and No time was given to prepare. Results were immediately announced. In my batch, only one got eliminated. So guys, be confident while putting your points. GUYS dont initiate take time get some valid point then talk (100% fluency expect) Topic: Indian education system,valentans day,BPO services,About Bank etc.... but i got eliminated at this round they taken 10:1 ratio.. its not my Day... but my friends are attend next round i had some remaining question forHR round.... 3. TECHNICAL HR Initially the HR was started with my project, I explained my project entirely. And he raised few questions from that. I answered for all those. So, you must have thorough knowledge of your project you had done. Besides, he raised questions like difference between array and Linked list then Stack, Queue from Data Structures, DBMS, and Operator Overloading, paging concept from Operating System, few concepts from Mobile Computing and some more. It took some 25-30 minutes for me. Depending on the panel, you will get questions. You brush up all the concepts from Data Structure, DBMS, Operating System and Programming Languages. If you are belonging to ECE, concentrate much on Microprocessor. (This info was given by my friend). You just give your answers if you are sure, otherwise, you say, sorry mam/sir, at present, I could not recollect. Do not try to give related or fake answers. CSC Placement Papers 1.
