Exam Pattern Overview

The Tier-I exam is a Computer Based Test (CBT) consisting of 100 Objective Type MCQs.

Section	No. of Questions	Marks	Duration
Part 1: General Mental Ability	25	25	2 Hours
Part 2: Technical Subject Related	75	75	(Composite)
Total	100	100	120 Mins

Note: There is a negative marking of 0.25 (1/4th) for every wrong answer.

Selection Stages

1. Tier-I: Online Written Exam (CBT).
2. Tier-II (Skill Test): Practical/Technical hands-on test based on your trade (30 Marks).
3. Tier-III (Interview): Personality Test and Interview (20 Marks).

Would you like me to find some specific recommended books or previous year’s topic-wise weightage for your specific technical branch?

To qualify for the Intelligence Bureau (IB) JIO-II/Tech position, you need to clear two different types of score benchmarks: the Minimum Qualifying Marks (the absolute baseline to stay in the race) and the Actual Cut-off Marks (the competitive score required to move to the next stage).

The IB JIO 2025 Tier-I results were just released on January 1, 2026. Below is the breakdown of the cut-off trends and qualifying criteria.

1. Minimum Qualifying Marks (Out of 100)

These are the mandatory scores you must achieve to even be considered for the merit list. Falling below these marks results in automatic disqualification.

Category	Minimum Qualifying Marks
UR (Unreserved)	35
EWS	35
OBC	34
SC / ST	33

---

2. Expected & Previous Year Cut-offs (Tier-I)

Since the official final cut-off varies based on the difficulty of the paper and the number of vacancies (394 for the 2025 cycle), actual cut-offs are significantly higher than the qualifying marks. Based on the 2025 exam held in October, here are the estimated cut-off ranges:

Category	Tier-I Cut-off Range (Approx.)
General (UR)	68 – 72
OBC	60 – 65
EWS	63 – 67
SC	50 – 55
ST	42 – 47

Note: For the Tier-II Skill Test, approximately 5 times the number of vacancies are shortlisted. This means for 394 vacancies, roughly 1,970 candidates are called for the next stage.

---

3. Factors Affecting the Cut-off

The cut-off is not fixed and changes every year due to:

• Difficulty Level: The 2023 and 2025 papers were rated as “Moderate,” keeping the cut-offs in the 65–70 range for UR.
• Vacancy Count: The 2023 cycle had 797 vacancies, while the 2025 cycle had 394, which naturally pushes the cut-off higher due to increased competition.
• Normalization: Since the exam is conducted in a Computer Based Test (CBT) format, normalization is applied if there are multiple shifts.

Next Steps

The Tier-I result for the 2025 cycle is now out. If your roll number is in the merit list, you should begin preparing for the Tier-II Skill Test (30 Marks) and Tier-III Interview (20 Marks).

Would you like me to find specific details on what kind of practical tasks are asked in the Tier-II Skill Test for your branch?

IB JIO Previous Year Cut Off Analysis

This video provides a professional analysis of historical cut-off trends and how they impact the preparation strategy for the Intelligence Bureau JIO exam.

The Tier-III Personal Interview is the final stage of the Intelligence Bureau (IB) JIO-II/Tech selection process. It carries 20 marks and is designed to assess your personality, mental alertness, and suitability for a career in national security.

Interview Structure & Key Areas

The interview panel typically consists of senior IB officers. They look for “officer-like qualities” and a calm temperament under pressure.

1. Personal & Background (HR Questions)

• Self-Introduction: “Tell us about yourself.” (Keep it professional, focusing on your education and technical background).
• Motivation: “Why do you want to join the Intelligence Bureau specifically, and not a private tech firm?”
• Home State/City: Be prepared to discuss the security or social issues of your native place.
• Stress Management: “How do you handle high-pressure situations or 24/7 duty cycles?”

2. Technical Knowledge (Application-Based)

Since this is a technical post, expect questions that bridge the gap between theory and intelligence work:

• Cybersecurity: Concepts of Encryption, Firewall, and how to prevent Cyber-attacks.
• Surveillance Tech: Role of GPS, RFID, and Sensors in intelligence gathering.
• Emerging Tech: “How can AI or Blockchain be used to enhance national security?”
• Practical Troubleshooting: If you are from ECE, they might ask how to use an Oscilloscope or troubleshoot a transmitter.

3. Intelligence & National Security Awareness

• IB vs. R&AW: Understand the difference (Internal vs. External intelligence).
• Current Affairs: Border disputes (e.g., LAC, LOC), internal security threats (Naxalism, Insurgency), and recent global conflicts.
• Security Terminology: Do you know the difference between Espionage and Sabotage?

Important Preparation Tips

• Review Your Application: The panel will have your Detailed Application Form (DAF). Any hobby or achievement mentioned is fair game for a question.
• Body Language: Maintain a formal posture, steady eye contact, and a polite tone. In the IB, “listening” is as important as “talking.”
• Honesty: If you don’t know a technical answer, it’s better to politely admit it than to guess. Integrity is a core requirement for the Bureau.

Tie-Breaking Rule

If two candidates have the same total marks, the IB uses a specific order to decide the rank:

1. Tier-I Marks (Highest priority)
2. Tier-II Marks
3. Tier-III (Interview) Marks
4. Date of Birth (Older candidate gets preference)

Would you like me to generate a list of 10-15 mock interview questions specifically tailored for your technical branch (Electronics or CS)?
