IISc Bangalore Interview Questions for SERC (Research) through GATE

Hi Friends,

This was my first interview experience which helped me to find the way ahead. I will add more to this list.

This is the experience of mine at IISc Bangalore for SERC (Supercomputer Education and Research Centre). I got a call from IISc Bangalore for SERC. They shortlisted the candidates based on the GATE rank.

I am writing all the IISc Bangalore interview questions as I remember.

IISc Bangalore Written Test for SERC

Firstly, there was a written test. They were having two batches per day with around 50 people each. They shortlisted around 12 from my batch for the second round of interview.

The written test consists of total 8 questions. We were asked to solve exactly 5 out of those.

And they told that if someone solves more than 5 they will consider the questions with least marks.

Questions were basically from programming logic (Two for loop condition and filling questions were there).

  1. They asked to fill blanks in the code for retrieving the lower triangular matrix stored in the single dimensional array.
  2. Some nested loop code with blanks in for loop.
  3. A question to prove to that spanning tree of n node graph has exactly n-1 component.
  4. Few questions from eigenvalues, matrices with definitions for the same.

For coding practice, try to solve common coding questions.
