Interview Preparation Tips

Interview preparation tips for other job seekers - Be prepared in Excel, SQL, and Python. The data provided may be unclear, so it is crucial to have a solid understanding of the core concepts, focusing primarily on Excel and SQL. The interviewer may not respond kindly if you don't answer their questions or if you seek clarification regarding the data or the questions posed. This behavior does not reflect professionalism. If anyone from 1DigitalStack comes across this, I kindly request that you provide training for your interviewers on maintaining professional conduct.

Interview Questions & Answers

Interview Preparation Tips

Round: Test
Experience: CAT type questions on maths and English. Speed matters. Preparation for CAT helps, I did not sit for CAT but I went through is DI material before the test to increase my speed. Questions in general are easy. Conduct yourself professionally. Deloitte decides to allot you a profile depending on your score in this test most probably. So make sure you do well in this test. I think the highest scoring candidates are shortlisted for the S&O profile, though I am not sure about it.
Tips: If you are up for a career in management consulting and can't possibly be shortlisted by Mckinsey or BCG, this is your golden opportunity. You have to do well in the test for it. Deloitte is one of the best places in the world for management consulting after MBB firms and I believe some people might have gotten selected for this profile just because they did well in this test (by fair or unfair means!!)

Round: Group Discussion
Experience: You are given a case. Your group of 10 has to find a solution for a client. The process lasts for about 30 minutes. The key is staying calm and composed and not disputing and challenging others violently! At the end you are supposed to give a presentation on the problem and it solution, 5 minutes for each member.
Tips: Speak less rather than speaking trash. Introduce yourself first when asked to give your part of the presentation and behave professionally, they check more on your professional behavior than the effectiveness of your solution. 50 % of the students passing this round generally make it to the offer. Hence this is the most important round. If you have done very well in this round you will probably do well in the PI.

Round: Behavorial Interview
Experience: Behavioral questions base on your resume.
I had networked a bit with my interviewer before the interview because both of us were waiting to enter the interview room and it felt awkward not talking to him. I think that might have helped.

Dont go for a technology profile hoping you will get to enter the management consulting space some day. Technology consulting is a good career choice only if you are passionate about it, or else it is a disaster, since the only exit route is an MBA application.
Dont go without reading about the company, it was a big source of worry for me
Tips: Answer the questions diplomatically. Appearing confident helps. I kept a smiling face no matter how tensed I was, that might help.
Know all the points in your resume and prepare to answer all behavioral questions you can possibly think of.
Have some questions to ask at the end of the interview.

General Tips: Its good if you have some extra academic involvement to have some discussion points during your PI. Or when you are asked about an achievement you are very proud of.
Skill Tips: I felt the company loves to hire calm and professional people who can articulate themselves properly. And do well in the written test if you want a profile of your choice.
Deloitte is probably the only company to be able to compete with the likes of Mckinsey in management consulting and IBM in technology, at the same time. No doubt, it is a great brand name to work with. It is highly rated in both the fields.
Strategy and Operations is a very good career if you are looking for management consulting, they have a program to train and sponsor you for the best B-Schools in the world.
The technology profiles are good if you are passionate about technology and its integration.
So be careful about your choices.
