Why pre-screen smart grid technicians before the interview
The awkward part of this role is that a fault can sit in the electrical plant, the communications link or the control system, and the symptom looks similar from the control room. Technicians worth hiring work through all three in order rather than assuming it is the part they know best. A short screen asks about a fault they traced, and about their switching discipline when someone is waiting.
What actually matters when screening Smart Grid Technician candidates
- 01
Hands-on competence
Check hands-on work with AMI meters (Itron, Landis+Gyr), RTUs, SEL relays, reclosers and capacitor bank controllers: ask about CT/PT wiring, DNP3 point mapping and field commissioning.
- 02
Safety discipline
Probe NFPA 70E arc flash boundaries, PPE category selection, lockout/tagout on 15kV distribution gear, and OSHA 1910.269 rules for switching and grounding practices.
- 03
Fault finding
Test troubleshooting of intermittent AMI mesh or cellular backhaul dropouts, failed head-end reads, SCADA point mismatches and recloser misoperations; ask how they isolated cause from symptom.
- 04
Reliability and conduct
Assess storm restoration callout history, truck stock and calibration discipline, work order closeout in the CMMS, and how they document as-built changes for the GIS team.
Pre-screening questions to ask Smart Grid Technician candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Equipment they know
3 questions01Explain your experience with supervisory control and data acquisition systems.
Listen forHands-on work with points, alarms and data quality rather than familiarity with a control room screen.
Experience limited to viewing displays, or no work with the field equipment behind the data.
02What experience do you have with remote terminal units and field devices?
Listen forDevices configured and commissioned by them, with point mapping and addressing understood in practice.
Devices replaced but never configured, or point lists treated as somebody else's responsibility.
03Describe any experience you have with distribution automation.
Listen forAutomated switching schemes understood, including what happens when a device fails to operate as expected.
Automation described conceptually, or no understanding of the fallback when a scheme misoperates.
Faults across layers
3 questions04Can you describe a time when you had to troubleshoot a network or grid issue?
Listen forElectrical, communications and control layers eliminated in turn, with evidence used at each step.
The fault assumed to be in their own specialism, or components replaced without diagnosis.
05What hardware and software tools do you use for diagnostics?
Listen forTest instruments and protocol analysers used competently, with readings interpreted rather than compared.
Diagnosis by substitution, or protocol tools carried but never actually used to isolate a fault.
06What challenges have you faced on past projects and how did you address them?
Listen forReal field difficulties such as poor communications coverage or legacy equipment, with practical resolutions.
Challenges described as scheduling, or no technical problem they had to work through on site.
Switching discipline
3 questions07How do you handle emergency situations relating to grid failures?
Listen forAuthorised switching procedures followed regardless of pressure, with control room instructions confirmed.
Switching described as adaptable under pressure, or actions taken without control room authorisation.
08What steps do you take to ensure compliance with industry standards?
Listen forStandards and operator procedures applied consistently, with work recorded to the required standard.
Compliance treated as paperwork, or records completed after the fact from memory.
09What methods do you use to ensure data integrity across the network?
Listen forField readings verified against control room values, with discrepancies investigated rather than accepted.
Telemetry trusted without field verification, or persistent bad points left unresolved.
Control system security
3 questions10What network and communication protocols are you familiar with?
Listen forUtility protocols understood in practice, with the ability to trace a message through the communications path.
Protocols named with no configuration experience, or no ability to diagnose a communications fault.
11How have you dealt with cybersecurity in your previous roles?
Listen forOperational technology treated separately, with removable media, remote access and vendor connections controlled.
Laptops moved between corporate and control networks, or vendor access left permanently open.
12Describe your experience with real-time monitoring and control systems.
Listen forAlarm handling understood, with nuisance alarms addressed rather than ignored or suppressed.
Alarms routinely acknowledged without investigation, or standing alarms accepted as normal.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Hands-on competence
35%5Names specific meter forms, relay models and DNP3 or Modbus point lists they configured, and describes commissioning tests they personally ran.
Safety discipline
30%5Describes a switching order or grounding step they refused or paused, citing arc flash labels, PPE class and the clearance process followed.
Fault finding
20%5Walks through a real outage or comms failure, showing how loggers, signal readings and OMS or ADMS data narrowed it to one component.
Reliability and conduct
15%5Shows consistent callout availability, clean closeout notes and redlines, plus examples of correcting bad records rather than passing them along.
The fault could be in the plant, the link or the control system, and the symptom looks the same. A one-way video screen asks how they work through it.

Process basics
How long should a pre-screening round for this role take?
Ten to fifteen minutes across eight to ten questions, answered async. Enough to establish their equipment experience, test fault diagnosis across the layers, and check safety and security practice.
What must be verified alongside the screen?
Electrical qualifications, switching authorisations and any site-specific competencies, in full. This work involves live distribution equipment and the authorisations are generally not transferable between network operators.
Evaluating answers
What is the strongest signal when screening this role?
A fault traced across electrical and communications layers. Technicians with real field time describe eliminating each in turn. Anyone who assumes the fault is in their own specialism will waste site visits.
How do I judge their safety discipline?
Ask about switching under time pressure. Sound answers treat authorisation and isolation as fixed. Anyone who describes shortcuts when the control room is waiting is a serious risk on live plant.
