The questions were quite tough and challenging. It was evident that the HR were expecting more talents for their company. I could answer about 40 questions and there were no negative marks so I answered all the questions. I was quite confident that the cutoff would be less that 40. We waited for the results of Aptitude Test. The result came around 2.30 PM. About 45 candidates were selected for the personal interview and I am glad that I am one of them.
