The first round was basically general aptitude. The questions are easy, you do not need to prepare for them. The only catch is the number of questions and the time. You have to solve 45 questions in 40 mins. After you clear the aptitude test, you are redirected to the machine interview round. They will ask you 8 questions. You will have 1 min to frame each of your answer and 3 mins to speak each. After you clear the machine interview, the next round will be the case study round. We were given a basic normal market entry question. You have to deduce the answers only from the given information. Do not assume anything. After solving the case you have to go for the interview. The interviewer will ask you about your approach. Remember, correct answers do matter. But the approach is also important. You will be redirected to the next round if your approach is correct. The next is Evidence-based interview. They will ask you guesstimates and puzzles. After that, you will have fit interview. This is about general HR questions.
