Interview Experience

When supported by proper credentials, words become more valuable!

Therefore, let's start with my introduction and required credentials. I am Ashish Kumar Sharma currently working at ISRO,Banglore. I was selected last year,2015. The purpose of this post is to share my personal interview experiences with all future aspirants.

Generally, two kinds of aspirants appear for the interview:

  1. Freshers

  2. Working professionals

The fields/domains from which various questions may be asked are as follows:

  1. Technical subjects:
    Prepare for 5 subjects properly (preferably include Programming & Data Structures, Algorithms, Computer Networks, Operating Systems). Try to embed real world examples in your answers. This will create an impact on the interviewer that you understand the concepts and are able to apply/relate them to real world scenarios. Additionally, a basic understanding of digital logic (counters and its type, registers) will be helpful.

  2. Project(s):

    1. If you are a fresher, then stay prepared to face questions from your final year project.The set of questions may include questions like scope of your project, what your project is all about (basically they just want to check that your basic idea about the project is clear or not). However, basic idea doesn't mean that they will not go deep into your project, they can try to explore the details if your project appears to be interesting to them. So, brush up and add some shine to your project related concepts; this will be your extra edge over those coming without proper revision.

    2. If you are an experienced person, the questions asked will be from your current company project(s). Additionally, they may enquire about the reasons for which you want to leave your current job. If you are not sure about answers to such questions, Google will provide you the answers. So, prepare, think or at least Google the various possible answers for such questions.

  3. Idea about ISRO(not necessary, but better to have!):
    Do you know what is PSLV, GSLV or do you remember basic formulas of conic section (circle, parabola, ellipse). Actually, some of my friends were asked to write these formulas. So, don’t forget to prepare accordingly.

The interview panel consists of 8 to 12 members. They may ask you to explain your answers on blackboard. Prepare yourself for explaining your answers on blackboard and while explaining try to include relevant diagrams (if possible) along with real world examples in your answer.

One of the common myths among many aspirants (which I personally found) is that ISRO interviewees are always bombarded with difficult questions. Trust me, it is not true! The interviewers just check your basic understanding of the subjects chosen by you. Of course, they may ask some difficult questions, but the probability of facing basic questions is around 80% (Mathematically, BASIC : TOUGH :: 4 : 1).  For any aspirant answering 70% of the questions the chances of getting selected is pretty good. Therefore, never ignore the basic concepts/questions to save time for the tough ones; master the basic ones first.

Everything I wrote above is related to preparation strategy but the lines written below (my morale boosters) are the fuel required for the brain and the mind to execute any strategy successfully:

  1. Nothing is impossible, the word itself says 'I'm possible'!

  2. F-E-A-R has two meanings: 'Forget Everything And Run' or 'Face Everything And Rise.' The choice is yours.

  3. Come and serve the nation and be the change that you want to see.

All The Best!
