I had gone as part of a walk in interview for freshers. After initial formalities, there was a written test. After the test, few people were selected for the next round. We were asked to write an essay. I thought this would be used in the interview later on, but my interviewer didn't even refer to the essay even once during the interview. There was no elimination based on the essay, and everyone was then moved to the interview with the HR/technical round. He had asked general question, like tell me about your self, the project that you worked on in the final year, how the things had been implemented, why do you want to join wipro, do you have any questions etc.
