Important: No Separate CERT-In Exam
This is the most important point for candidates preparing for the recruitment.
CERT-In Scientist-B 2026 does not require preparation for a separate CBT/written test conducted by CERT-In. The recruitment uses GATE scores for shortlisting. Shortlisted candidates then undergo document verification and Personal Interaction/Interview.
Consequently, your GATE preparation is your primary written-examination preparation for CERT-In Scientist-B.
CERT-In Scientist-B Interview Preparation
Candidates should also prepare for the Personal Interaction because it contributes 40% to the final merit.
For the interview, focus on:
- Core subjects from your qualifying degree
- GATE concepts
- Cybersecurity fundamentals
- Information security
- Network security
- Vulnerability assessment
- Incident response
- Malware and cyber threats
- Cryptography
- Cloud security
- Current cybersecurity developments
- CERT-In’s role in India’s cyber-security ecosystem
Candidates can also familiarize themselves with CERT-In’s official advisories and cybersecurity directions because the organisation’s work covers cyber-security incident response and information-security practices.
