What is the most common electrical engineering interview mistake?

Giving a memorized-sounding, surface-level answer to a fundamentals question instead of demonstrating actual reasoning — for example, stating "multiply by root 3" for three-phase calculations without being able to explain where that factor actually comes from. Interviewers are testing understanding, not recall.

How should I answer a behavioral question about a design change during construction?

Structure the answer around what the original design assumed, what conflicting condition was discovered in the field, how you assessed the impact, how you communicated the change to relevant parties, and the outcome — while avoiding language that assigns blame rather than showing problem-solving.

Do utility interviews differ significantly from consulting firm interviews?

Yes. Utilities tend to emphasize system-level protection coordination, reliability metrics, and safety culture (NFPA 70E, arc flash, lockout/tagout) more heavily. Consulting firms tend to emphasize client communication, multi-discipline coordination, and technical breadth across varied project types.

Should I bring up a disagreement with a code inspector in an interview?

Yes, if asked about it — but frame it around researching the code thoroughly, understanding the inspector's underlying concern, and working collaboratively toward a resolution. Answers that sound adversarial toward AHJs are viewed as a red flag, since working productively with inspectors is a routine part of the job.

What kind of questions should I ask the interviewer?

Ask questions that show genuine engagement — typical project timelines from design through commissioning, how the team handles code interpretation disputes, what tools (like ETAP or specific drafting software) the team uses, and how PE licensure is supported. Avoid questions easily answered by the company's public website.

What Electrical Engineering Interviews Are Actually Testing For

Electrical engineering interviews at any employer type are testing two things at once: whether you actually understand the fundamentals well enough to reason through a problem you haven't memorized the answer to, and whether you can communicate that reasoning clearly to a non-specialist (a project manager, a client, an inspector) as well as a fellow engineer. Strong candidates lose points less often on knowing the material and more often on giving a vague or memorized-sounding answer instead of demonstrating actual reasoning. The examples below show the difference.
