Introduction
Mechanical engineering remains one of the most sought-after core disciplines in India. Every year, lakhs of graduates aspire to join Public Sector Undertakings (PSUs) due to their job security, prestige, technical exposure, and benefits.
While GATE is the primary gateway, many engineers are unaware that several PSUs and government research organizations recruit Mechanical engineers without GATE. These opportunities come in the form of dedicated exams, interviews, and apprentice programs.
This guide explores all PSU and government opportunities without GATE for Mechanical engineers — including eligibility, recruitment process, cutoff trends, salary, and preparation strategies.
Recruitment Modes in PSUs
- Through GATE: ONGC, IOCL, NTPC, GAIL, BPCL, HPCL, etc.
- Without GATE: Specialized exams & interviews by ISRO, BARC, HAL, BEL, SAIL, DRDO, NPCIL, etc.
Here, we cover the non-GATE route.
