IndianOil Recruitment 2026 Selection Process
The selection process consists of three major stages:
- Computer Based Test (CBT)
- Group Discussion (GD) and Group Task (GT)
- Personal Interview (PI)
Candidates first appear for the CBT. Shortlisting for GD, GT and PI is based on CBT marks arranged in descending order for the respective domain. Simply qualifying in the CBT does not guarantee an invitation to the next stages.
IndianOil CBT Exam Pattern 2026
The Computer Based Test contains 100 objective multiple-choice questions.
Section A – General Aptitude
| Subject | Questions |
| Quantitative Aptitude | 20 |
| Logical Reasoning | 15 |

| Total | 50 |
The General Aptitude section is allotted 60 minutes.

Therefore, the complete CBT consists of:
- 100 questions
- 50 General Aptitude questions
- 50 Domain Knowledge questions
- 150 minutes total standard examination time
PwBD candidates eligible for compensatory time may receive additional examination time according to the applicable provisions.
IndianOil CBT Negative Marking
Each question carries 1 mark.
For every incorrect answer:
0.25 marks will be deducted.
The examination sections have a fixed order:
Section A → Section B
Candidates should therefore plan their attempts carefully because incorrect answers carry negative marking.

Candidates must secure:
- 40% in Section A
- 40% in Section B
- 45% overall

- 35% in Section B
- 40% overall
PwBD
Candidates must secure:
- 25% in Section A
- 25% in Section B
- 30% overall
However, merely crossing these minimum marks does not guarantee shortlisting for GD, GT and PI because candidates are ranked according to CBT marks.
IndianOil Final Merit List 2026
The final merit list is prepared using a composite score from the different selection stages.
| Selection Component | Weightage |
| Computer Based Test | 85% |
| Group Discussion & Group Task | 5% |

Minimum pass marks are prescribed separately for GD/GT and PI.
The composite score minimum is:
- General/EWS/OBC(NCL): 45%

Therefore, the CBT is the most important component because it carries 85% weightage in the final merit calculation.

IndianOil Recruitment 2026 – Special Note for CSE/IT Candidates
For Computer Science and Information Technology graduates, this recruitment is particularly important because the notification recognizes a broad range of CSE, IT, AI, Data Science, Cyber Security, Software Engineering and related degree titles.
However, candidates should not apply only because their course sounds similar. IndianOil specifically states that candidates whose qualifying discipline is not among the listed disciplines may not be eligible, although the Corporation reserves the right to take a final decision in certain cases.
Therefore, candidates should compare the exact wording on their degree certificate with the eligible discipline list before applying.
IndianOil Recruitment 2026 – Exam Preparation Strategy
The CBT has two major areas:
Part 1: General Aptitude
Focus on:
- Quantitative Aptitude

Part 2: Domain Knowledge
The second section contains 50 questions based on the candidate’s respective domain.
For engineering candidates, preparation should be based on the domain syllabus provided by IndianOil along with the detailed recruitment information.
