  • Data Structures and Algorithms

  • DBMS
  • Computer Networks
  • Compiler Design
  • Theory of Computation
  • Digital Logic Design
  • Engineering Mathematics
  • Discrete Mathematics and Graph Theory
  • Software Engineering
  • Network Security
  • Web Technology

The level of questions is similar to GATE. Moreover, many times ISRO has repeated the previous year gate questions so, practice gate questions of last 10-15 years. Also, as accuracy plays a great role, so practice as many questions as possible. Try to give mock tests and keep track of the time you are investing in each question. All the topics are equally important. ISRO asks questions from almost all of these topics. So try to cover the entire syllabus.

Tips for Interview

  • Prepare for all the above-mentioned computer science subjects pretty well.
  • Do not ignore subjects like Software Engineering, web technology which are not asked in GATE, but they may be asked here.
  • One question is always from Programming Languages. When asked for a programming language, always tell that language in which you are most comfortable. It is not the case that if one tells Python or Java, he/she will be in an advantageous position.
  • Study your B.Tech project deeply. You must know the concepts behind it and its applications.

One more important point is that be confident and honest with your answers. Also have basic knowledge of ISRO’s future projects, ISRO annual budget, founder of ISRO, etc. You may also be asked about your current employment and why you want to join ISRO.
