Interview Preparation Tips

Round: CGPA SHORTlist
Experience: They selected students who have CGPA greater than 8.5.After the selection was done,we had skype interviews where each student was given a slot.In the interview they ask you about 'tell me about yourself',your projects.You should explain the projects exactly and clearly.They ask you better alternatives for implementing the project.After that on the basis of the project they ask you questions related to that subject.Data structures is very important.After the questions on projects were asked they ask you to write programs on data structures(simple programs). They asked me a program to reverse a singly linked list. After that,if they are impressed with it,they go for databases.One should be thorough with functionalities of each key.If time permits they may ask you puzzles(some of my friends were asked). Quite an easy interview.They give you enough time to think so no worries.People with some interview experience can easily crack this.The main objective of the interviewer is he/she checks whether the student is perfect in the concepts learned.
Tips: Don't be panic.If you don't know anything directly say 'I don't know'. They ask you very easy questions.
