Interview Information

Dear Student,

Congratulations on being selected to be interviewed for admission to the research programme at ECE, IISc. Our department is one among the top ECE departments in the country with faculty members that have rich academic and industry experience from leading universities and companies. The research programme at ECE, IISc, gives the student an opportunity to solve challenging problems that will impact the development of future technologies.

You would have received a letter from our admissions office inviting you to an interview at IISc during 6-10 June 2016 for admission to our research programme. I am writing this letter to inform you about the interview procedure in our department, so that you can prepare well for it.

Upon arrival, you will be asked to indicate one or two proposed research areas based on your research interests. A sample list of areas is attached.

All candidates, across all research areas, will be examined on their analytical ability in two of the following areas of basic mathematics:

  • Calculus and Differential Equations
  • Matrix Analysis and Linear Algebra
  • Fourier, Laplace, and z-Transforms
  • Probability Theory and Random Processes
  • Discrete Mathematics (combinatorics, graphs).

You will also be asked to indicate two of the above areas on which you will be tested.

Our interview process consists of an initial written test. The written test will be on the two areas of basic mathematics that you chose. The written test will be of 30 minutes duration starting at 9:15 am (for those asked to report at 9:00 am), and starting at 2:15 pm (for those asked to report at 2:00 pm) on each day. Please allow for traffic delays, and for travel within the IISc campus, to ensure that you are at the ECE department main lobby, IISc, at your reporting time.

A sample set of questions on each topic can be found here.

The written test will be followed by an oral interview for those candidates shortlisted based on their performance in the written test.

In the oral interview, you may be asked further questions on the chosen mathematics topics. The problems posed will not involve lengthy calculations, but will test the basics, and the ability to think “on one’s feet”. You may also be asked questions in the proposed area of research or any related area. These questions will be from topics of undergraduate study and topics of post-graduate study (if applicable). The nature of the questions will be to explore the student’s clarity of thought and depth of understanding of the topics, rather than descriptive system level knowledge.

Please familiarise yourself with the interview process.

I look forward to seeing you.

With best wishes,


(K. V. S. HARI)
