BARC Exam Pattern | Or Selection Process

What is the selection process for the BARC scientific officer?

First of all, you have to clear the GATE exam with a good rank.

After that, to get selected in the BARC, you need to pass through all four stages.

Let’s proceed through the four important stages.

1. Online Written Examination:

The exam is composed of multiple-choice questions (MCQs) that cover technical subjects relevant to electrical engineering.

2. Interview:

For the interview stage, candidates are shortlisted based on their performance in the Online Written Examination.

This stage comprises both personal and technical interview rounds.

3. GATE Score Requirement:

A competitive GATE (Graduate Aptitude Test in Engineering) score is required, preferably with a high rank.

4. Final Round or Selection Process:

The final selection depends on the performance of both the written exam and the interview.

Hopefully, the mentioned BARC Scientific Officer exam syllabus and exam pattern for electrical engineering will be beneficial for your preparation. For the latest updates and detailed syllabus, please visit the official BARC website.
