Neudesic Associate Consultant interview questions

I recently interviewed at Neudesic's Kochi office, where the first round was a written aptitude test. The test consisted of 15 questions, but one of the questions was incorrect. The instructors informed us to disregard that particular question. After completing the test, they collect the sheets and exchange with other candidates for review. The instructors then collected the papers, but here's the puzzling part: they only considered papers with 9 or more correct answers, without even reviewing the remaining papers. I'm still unsure about the logic behind having candidates review each other's papers. I'm confident that I scored 9 or above, but unfortunately, I didn't clear the exam. It's possible that I made a mistake or the person reviewing my paper mischecked my answers. Regardless, the experience was certainly memorable, not in a positive way."
