How to hire a Maintenance Technician
Maintenance technicians keep plant equipment running - performing preventive maintenance, diagnosing breakdowns, handling electrical and mechanical repairs, and tracking machine uptime. In Indian manufacturing, where many plants run aging equipment 24/7 and unplanned downtime directly hits production targets, a skilled maintenance technician is the difference between a line that runs at 85% availability and one that limps at 60%.
Why this role is hard to hire
The hiring challenge
Maintenance technician hiring is difficult because the real skill is diagnostic, not just repair. Many candidates can replace a part or reset a machine, but few can systematically troubleshoot a failure they have never seen before. The interview needs to test for diagnostic reasoning (can they isolate whether a failure is electrical, mechanical, pneumatic, or PLC-related?), preventive maintenance discipline (do they follow PM schedules or only fix what is already broken?), and documentation habits (do they log breakdowns, parts used, and MTTR, or do they fix and forget?).
What to look for in a Maintenance Technician
Three traits matter most: Diagnostic methodology (when a machine goes down, do they follow a structured troubleshooting approach - check symptoms, isolate subsystems, test hypotheses - or do they start swapping parts randomly?). Preventive maintenance commitment (do they take PM schedules seriously and complete them properly, or do they treat PM as a formality that gets skipped when production is busy?). Learning orientation (manufacturing equipment evolves - PLCs, VFDs, servo motors, IoT sensors - does the candidate actively learn new technologies, or are they stuck in purely mechanical-era thinking?).
For Indian plants specifically, test for comfort with the actual equipment on your floor (many Indian plants run a mix of Indian, Japanese, German, and Chinese machines - each with different control systems and spare part ecosystems), electrical safety knowledge (electrical hazards are the leading cause of maintenance worker injuries in Indian factories), and spares management awareness (in India, lead times for imported spares can be 8-12 weeks - a good technician anticipates what they will need and flags it early).
The best maintenance technicians track MTTR and MTBF for their machines and can tell you which equipment is trending toward failure. Candidates who only talk about "fixing breakdowns quickly" without mentioning trends, PM compliance, or reliability improvement are reactive technicians, not proactive ones.
Common mistakes when hiring Maintenance Technicians
Testing for knowledge instead of diagnostic ability. Asking a candidate to explain how a motor works tests memory. Giving them a failure scenario and asking them to walk through their troubleshooting steps tests the skill you actually need. Use scenario-based questions that require structured diagnosis.
Ignoring electrical safety. Electrical work is the most dangerous part of maintenance. Ask the candidate about lockout-tagout procedures, how they verify de-energisation before working on equipment, and what they do if asked to work on a live panel. Candidates who are casual about electrical safety are a liability.

Sample questions
What a great interview looks like
"A production line motor is tripping repeatedly after 10 minutes of operation. Walk me through your troubleshooting steps from start to finish."
"You arrive for the morning shift and find that three PM tasks are overdue and a machine has just broken down. How do you prioritise your day?"
"The production supervisor says: "Skip the PM on machine 4 today - we cannot afford the downtime. Just do it next week." Respond."
"A VFD displays an overcurrent fault on a conveyor motor. Which of the following should you check FIRST?"
"Tell me about a recurring breakdown you solved permanently. What was the failure pattern, what did you diagnose, and what was the fix?"
