Round: Guesstimate Interview
Experience: This was the first round of four interviews that I altogether faced. The above three questions were asked to me serially. But before that, I had been asked to give a brief introduction of me. I had solved all three of them. The first question didn't take much time. Since I am not that interested in solving puzzles, I took some time in solving the second question but eventually I did it. The third question is a guesstimate. I started solving it with the inputs being given by the interviewer and I moved closer and closer to a realistic range as per the data inputs that were given to me.
Tips: The practice that I did for aptitude helped me in solving the first question. That's why putting in a little effort in improving your aptitude skills will ultimately help you. The puzzle questions can be found on the internet and you just have to go through them once. After a while, you will be well acquainted with them and you won't face any problem in solving them. And for the guesstimate, the best option you have is Google. Surf the internet and you will get loads of them and how to approach them. They are the questions that are used to check how you approach a problem.

Round: Puzzle Interview
Experience: This was my second round in which I was asked only two question and both were puzzles. I could answer both but my approach in the second question was wrong first. The interviewer made me clear and then asked me to answer. After the questions, we had a conversation on my doubts regarding the work and the company.
Tips: The puzzles as I already said can be practiced from the internet. But the most important point is you need to clearly understand the question before answering them. The second question was a conventional one but with a twist, which actually checks how attentive you are. So you need to hear and understand the questions properly. In case you do not understand in the first go, ask your interviewer to pardon again.

Round: Case Study Interview
Experience: The third interview consisted of a simple probability question and a case study. The case was a Cement Company in India that was losing its market share and I had to describe the reasons considering the constraints were given to me.
Tips: You can easily get the examples of case study problems along with the ways of solving them, on the internet. The most important thing is you need to think out of the box of all the possibilities to analyze the case from an unconventional domain.

Round: HR Interview
Experience: This round was taken by two persons simultaneously. There was one puzzle asked and the rest of the interview went on with general HR questions and answers.
Tips: HR rounds are the easiest of all in the interviews of technical companies. You only need to prove what you say. There must be no contrast in what you speak and what you think at that point of time. At no instance of the interview you must contradict yourself.
