255 online tests available for IOCL Civil Engineer on CIVILGYAN — 2 free.

Indian Oil Corporation Limited (IOCL) — a Maharatna Central PSU and India's flagship energy company — recruits civil engineers as Executives (Graduate Engineer, Grade A) through its own Computer Based Test (CBT). This is a shift from the earlier GATE-score route: IOCL now sets and conducts the exam itself, so your preparation targets the IOCL CBT pattern directly.

The CBT has 100 objective questions in 150 minutes, split into Section A (General Aptitude — 50 Q) and Section B (Domain Knowledge, Civil Engineering — 50 Q). Each correct answer earns 1 mark and every wrong answer costs 0.25 marks. Section A comes first, then Section B.

Shortlisting for the next stages is on CBT marks (subject to section-wise and overall cut-offs). Final selection combines CBT (85% weight), Group Discussion + Group Task (5%) and Personal Interview (10%).

How to Prepare for IOCL Civil Engineer

  1. 1Split your prep 50-50: Section A (aptitude) is half the paper, so don't treat it as an afterthought — daily quant, reasoning and English practice pays off.
  2. 2For Section B, master the high-weight civil subjects (Structural, Geotech, Environmental, Fluid Mechanics) with concept + numerical practice; the level is comparable to GATE/PSU civil.
  3. 3Respect the 0.25 negative marking — attempt only what you're reasonably sure of and avoid blind guessing, especially in the domain section.
  4. 4Practise full-length 100-question mocks in 150 minutes to build section-wise time discipline (60 min for A, 90 min for B).
  5. 5Track the IOCL careers page (iocl.com) for the exact vacancy count, reservation and any pattern updates before the CBT.
