I applied for the Production Engineer position at Transformers and Rectifiers India Ltd through my college placement portal. There was no written test — the process started directly with resume shortlisting, followed by an interview. Interview Process Breakdown 1. Self-Introduction The interview began with a basic introduction about my background, education, and interests. 2. Technical – Transformers Basics They asked what I knew about transformers. I explained: Basic working principle Purpose of transformers Major parts like core, windings, insulation, oil tank, conservator, bushings, etc. They were checking fundamental understanding — not deep electrical theory. 3. Technical – Welding Processes (Major Focus) This was the most important part of the interview. They asked about: Different welding processes (Arc welding, MIG, TIG, etc.) Specific function of each process Where each welding method is used in manufacturing/fabrication They were clearly looking for practical manufacturing knowledge, not just textbook definitions. 4. HR/Operational Question Finally, they asked whether I was willing to relocate to Gujarat, since their manufacturing facilities are based there.
