Interview
For people with more then 8.5 CGPA, there is direct interview which is a mixture of both technical and HR. They mostly ask questions from resume and your area of interest. Don't drag answers. Just say up to the point and it'll be over within 10 minutes. If you drag without knowing the answer, they just keep asking questions from your answer.
