ONGC's Graduate Trainee interview is a core-engineering PSU round focused on upstream oil-and-gas fundamentals and honest readiness for field postings.
In 2026 expect a technical round that ties your branch (petroleum, mechanical, chemical, or geoscience) to drilling and production (fluid mechanics, reservoir concepts, equipment), and an HR round that directly probes willingness for offshore, Assam, or remote-site postings in the early years. ONGC's work is field-heavy, so interviewers reward candidates who connect theory to upstream operations and have genuinely thought through the posting reality rather than giving a reflexive yes. Revise your core subjects with a drilling-and-production lens and prepare a candid answer on remote and offshore work.

Common mistake:Saying "we did X" throughout. Interviewers score your individual contribution. If you can't separate what you did from what the team did, it signals low ownership.
