Interview Preparation Tips

Round: Test
Experience: Deloitte selection procedure involves a written test which is
same as CAT format (certainly not that tough). Though I had not joined any test series to prepare for it, but I must strongly recommend that you should actually join a test series (provided by Career Launcher or
TIME). This test series will actually help you to synchronize your mind to the format and moreover it would help to refresh the question solving skills which you used to exercise while preparing for JEE.

Round: Group Discussion
Experience: general topic is given (mostly it is as to how you would go for implementing a new type of technology in a company, and hence you all have to decide the stepwise procedure for the implementation), then whole of the group is called in presentation room where each one is told personally to speak about the same topic as that of GD. This constitutes
second round. Finally, if you clear it, you get to face the interviews.
Tips: From now onwards, start reading newspaper daily. Just give at least one hour reading the editorials from newspaper and make it your habit. Not only for GD's, but for life in general, its very important that you should have a certain view about things happening around you and in the world and newspapers are the best thing which help you form your views and also know about the expert opinions on day to day topics. So, make sure that you read newspaper daily.

Round: Other Interview
Experience: For interview, main thing is that you should be well conversed about everything you have mentioned on your resume. So, before you go for any interview, just make sure that you can speak about for 5 minutes on
every single thing in resume. Deloitte is a company which is open for all the btech students and hence its mainly looking for the students who have a right attitude and are good at their interests.
Tips: have a perfect set of communication skills. I had not done
any special type of preparations for the interview or group discussions but all these skills actually developed during these years. I would advise that in order to gain more confidence at speaking, you should start taking challenges from now on and should actively participate in any sort of debates and GD.

Interview Preparation Tips

Round: Resume Shortlist
Experience: I had sent my resume to the hiring group, Selection through telephonic interviews. I was interviewed by three different research groups  (once by each).
Tips: Factors in decreasing order of importance: CGPA each stage. Ability to explain your projects precisely. Ability to solve ''standard" logarithmic problems.  The way you think and put down your Answer is the most important. The final answer .s not so I important, and they prod you when you think out aloud anyway.

Round: Technical Interview
Experience: Almost- by default they ask about your previous projects/internships if they are relevant to the group. Ofher questions depend on the group you are interviewed by and your own profile, In my case it was machine learning, text mining etc. I was told about the research problem they were dealing with then and asked f or comments/suggestions/.inputs and a discussion followed.
Tips: Basically these are specialized Interviews so it's good to have sound knowledge of your domain (analytical and application skills are very much required).

Skill Tips: CGPA>9.0, 1f not (like me) relevant work done in the domain and in past internship.A recommendation from the professor is also a good add on.
