Round: Resume Shortlist
Experience: For resume preparation I took help from my seniors as well as batch mates. A very effective method which I got to know from a senior was to first make a list of all the different activities I have done in my life and then writing down, corresponding to each of them, what quality of mine is getting highlighted and what would I like to get highlighted. After preparing this list I could clearly see what are my strengths and how can I highlight them. Then came the writing part, generally there is a perception that you should first write your academic projects and then extra curricular activities. But what I have learnt is that you need to show on your first page something that will make the person look at your second page also, otherwise the resume reviewers don’t have much time that they can go through every resume completely. You need to show something interesting may be academics or may be extra curricular activities. Also, a very important consideration is the company you are applying to. You should show in your resume what the company is looking for. For instance if a company is looking for a technical profile then obviously they will be more interested in your academic achievements and not extra-curricular activities.
Tips: Taking help from the resumes of some successful seniors is a nice way to start. Later on you can mold it according to yourself .Also, it is very necessary to get the resume reviewed at least 3-4 times by someone.

Round: Group Discussion
Experience: It had a GD first and then an interview. For GDs I had a few practice sessions with my friends and since I had joined TIME for CAT coaching, so I had some GD sessions there also. The first round was a GD session. There were eight people in my group. The topic given was “Role of Media in the society”. The judges of the GD session were also a part of the GD and it was made clear that no shouting and no stopping others is acceptable. So overall it was a nice discussion for about 40-45 minutes. After the session judges called a few people in the room one by one. I was also called and asked my opinion about the company and would I like to join.

Round: Interview
Experience: The second round was an interview. I was asked general HR questions like “why I came to IIT” and “what are my future plans” and then one or two resume based questions. Then they asked me 2 puzzles, one was a probability related puzzle with fair and unfair coins. Overall I had a very small interview of only 20 minutes compared to few other people’s interviews. I though I was going to make through but it was the other way round.

General Tips: If someone is appearing for any of the Data Analytics and Consulting firms, he should be very nicely prepared for the typical HR questions, just feel confident and speak what your heart says. He should be very thorough about whatever he has written in the resume. Also, puzzles are very important part for such interviews, so practicing general puzzles from internet would be very helpful. And if someone is appearing for a core company, be ready for very basic technical question of your field.
