Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about a time you caught an error in a dataset that other people had been relying on.

What they are checking: Their attention to detail and whether they own the fix and tell the people affected.

Describe the most complicated mapping or GIS project you've worked on and what you personally did.

What they are checking: The depth of their real hands-on GIS experience and how clearly they can explain their own part.

How do you work with field crews who are frustrated that the maps they use are wrong?

What they are checking: Whether they can keep a good working relationship with crews, since crews are their main source of corrections.

What would you do

A field crew sends a correction saying a transformer is on a different pole than the map shows. How do you decide whether to change the map?

What they are checking: Whether they verify field corrections before editing, since a wrong fix is as dangerous as no fix.

An as-built print is missing the depth and material of a new service line. What do you do?

What they are checking: Whether they chase down missing facts from engineering or the crew rather than guessing and filling it in.

You have a backlog of field corrections and a rush request from engineering for a new subdivision map. How do you handle it?

What they are checking: How they balance urgent work against a backlog that quietly makes the system less accurate.

What steps do you take when two as-built prints for the same area seem to conflict?

What they are checking: Whether they reconcile records methodically and document their decision for the next person.

About the work

Walk me through how you'd post a gas main replacement in ArcFM from an as-built print, from the moment the print lands on your desk.

What they are checking: Whether they know the real editing workflow in ArcFM, not just the idea of updating a map.

What's the difference between how a gas distribution network and an electric distribution network are modeled in a utility GIS?

What they are checking: Whether they understand connectivity, phasing and pressure systems well enough to keep both networks trustworthy.

How do you check the topology and connectivity of your edits before you post them to the default version?

What they are checking: Whether they use QA tools and validation rules instead of trusting their eye.

Why does map accuracy matter for a gas utility from a safety and regulatory point of view?

What they are checking: Whether they connect mapping to locates, emergency response and pipeline safety rules, not just neat maps.
