Interview: Technical interview to assess practical knowledge

The ISRO exam is conducted by the ISRO Centralized Recruitment Board (ICRB) to select candidates for various technical positions in fields such as Civil, Electrical, Mechanical, Electronics, and Computer Science. The recruitment process consists of two main stages: a written examination and an interview. The written exam consists of multiple-choice questions (MCQs) divided into two sections: Core Engineering (80 marks) and General Aptitude (20 marks). The interview is a technical interview to assess the candidate's practical knowledge. Here are some tips to prepare for the technical interview for the ISRO electrical exam:

  • Understand the syllabus and focus areas: Start by understanding the syllabus and key topics that will be covered in the interview. Focus on the core subjects related to electrical engineering, such as Digital Electronics, Analog Electronics, Control Systems, Communication Systems, and Microprocessors.
  • Build strong conceptual knowledge: The interview will assess your practical knowledge and understanding of various concepts. Focus on building strong conceptual knowledge by studying recommended books and resources. "A Course in Electrical and Electronic Measurements and Instrumentation" by A.K. Sawhney and "Electrical Machinery" by P. S. Bimbhra are suggested as useful preparation materials.
  • Practice numerical problems: Electrical engineering interviews often include numerical problems. Regularly practice solving numerical problems related to electrical engineering concepts to improve your problem-solving skills.
  • Stay updated with the latest advancements: Keep yourself updated with the latest technology and advancements in the field of electrical engineering. Stay informed about current affairs in science and technology, especially in the field of space research and innovation.
  • Solve previous interview questions: Practice solving previous interview questions asked in ISRO electrical engineering interviews. This will help you understand the type of questions asked and improve your preparation.
  • Prepare for technical and theoretical knowledge: The interview will assess your technical and theoretical knowledge in electrical engineering. Make sure you have a thorough understanding of the fundamental and advanced concepts in your specialization.

Remember that the interview carries more weight in the ISRO exam selection process, so focus on strengthening your conceptual knowledge and practical application skills. Utilize your preparation time effectively and consider signing up for daily updates on science and technology current affairs.
