Interview questions: Electrical Project Manager, Data Center
Data Center Headhunters recruits critical facilities, data center operations, construction and delivery, commissioning, power and cooling, and executive talent for colocation, hyperscale and enterprise sites. We research the market, contact working people and qualify a shortlist for your opening. No upfront fee. You pay only if you hire.
These questions are for a hiring manager testing an electrical project manager on data center work, and they aim at what the person decided, paid for and signed rather than what the résumé says.

What does this hire really come down to?
An electrical project manager holds the contract for the electrical scope, which means cost, schedule, change orders and the owner conversation. They do not direct crews hour by hour, and a good one knows where that line sits. Strong answers are specific about numbers they managed in general terms, the people they dealt with and the mistakes they made.
Weak answers describe teams without naming decisions.
What do we check before you see anyone?
Credential questions should be about what a card proves. OSHA Outreach is a course completion record. NFPA 70E training does not by itself show who the employer treats as qualified. Ask how the person determined who worked on energized equipment.
- Credential questions should be about what a card proves. OSHA Outreach is a course completion record. NFPA 70E training does not by itself show who the employer treats as qualified. Ask how the person determined who worked on energized equipment.
- Ask about licenses by jurisdiction. A master electrician qualifier is not the same as a project manager, and the person should know who signed which permits.
Where do we find these candidates?
Typical backgrounds include electrical contractors, industrial and utility project managers, and engineers who moved into management. Ask which size of job each background involved, since a project manager on a small tenant fit out may not have managed large gear procurement.
Which hiring mistakes should you avoid?
- Accepting talk about teamwork as an answer to a question about cost. Ask for the decision.
- Skipping questions about failure. A manager who cannot describe a loss has not carried one.
How the search runs
Open with scope
Ask what they were accountable for, then what they merely supported.
Questions on commercial control
Walk me through how you bought the switchgear and what happened when the delivery date moved. Listen for how they protected the schedule, who they notified and whether the owner agreed to any change.
Describe a change order you refused to price and why. Describe one you priced too low.
How did you track labor against what the estimate assumed, and what did you do when it drifted? Look for a weekly practice.
Questions on field and commissioning
How did you coordinate shutdowns or tie ins with the owner's operations team? Listen for who approved the procedure and who was present.
What did the testing and commissioning agent find on your last job that you had missed? A candid answer shows maturity.
Tell me about a time a foreman and an engineer disagreed and you had to decide. Ask what the outcome was.
Questions on the owner and the team
Describe the hardest conversation you had with an owner representative. What did you give up and what did you hold?
Who on your team did you promote, and who did you move out?
Questions on procurement and gear
How did you manage long lead equipment, and what did you do when a manufacturer slipped a date? Ask who they told first.
Describe how you verified that delivered gear matched the approved submittal.
Red flags to listen for
Answers that give credit to the whole team for every success, while blaming the owner for every miss, tend to come from people who did not hold the decision.
Questions on closeout
How did you manage punch lists, test records and turnover documents for the electrical scope? Ask what the owner rejected.
Which warranty issue came back after turnover, and how did you respond?
Close by asking what they would do differently on their last project if they began again tomorrow. Pay attention to whether the lesson concerns their own decisions or other people's failings, and whether it costs them anything to say.
Questions
How would you test a candidate on switchgear lead times?
Ask when they bought the main breakers and what they did when the date moved. A good answer names the manufacturer contact they pressed, the temporary arrangements they proposed and what the owner approved.
What should a candidate say about paralleling generators with the utility?
Ask who wrote the sequence of operations and who attended the load bank test. A strong candidate describes the transfer tests they witnessed, not only that the generators ran.
How do we probe their handling of a failed megger or cable test?
Ask what the reading was, who found it and what the repair cost the schedule. Candidates who held the scope recall the cable run and the pulling crew by name.
What reveals whether they understand busway and PDU coordination?
Ask where the busway tap boxes landed relative to rack rows and what changed after the owner moved a row. Weak answers describe the model while strong ones describe a field walk with the foreman.
How should they describe a live tie in to an energized board?
They should name the procedure author, the person who held switching authority and the work window agreed with operations. Anyone vague about who performed the shutdown likely watched rather than ran it.
What does a good answer about commissioning findings sound like?
They should describe an actual finding, such as a mislabeled breaker or a failed relay setting, and what they changed in later work. Beware of answers claiming nothing was found.
