Round: Technical Interview
Experience: Were asked simple questions and program them like reversing string without temporary variables, finding the earlier date when entered as string and finding the difference in number of days between them.
I was asked to explain him my internship project in great detail and above all one should be prepared to answer the question 'Why IT?' if from a non IT background. Then I was asked to program a logic for 'Search and replace" tool of MS Word.
Round: HR Interview
Experience: Was asked about my background in detail and stressed again and again on 'Why IT?'. Then he asked me to prepare a summary on the merits and demerits of various Employee Data Management techniques for an organisation. For the end of the interview you should have a question which you would ask to the interviewer.
General Tips: Don't try to over emphasize the correctness of your logic if the interviewer finds a glitch. It irritates him. Be interactive in your HR round. In our case it was the VP of Oracle India who took the final round. So I asked him about his experience in the company. He was very happy to share it with me. But asses your interviewer before you put forth these queries cause your interviewer might not be as jolly as mine was.
