Imagine a colleague wanted to take a different approach on a project instead of your idea. How would you respond to this situation?

Electrical engineers typically work with project managers, designers, and other engineers. When designing, testing, or manufacturing an electrical system, they may disagree on how to solve issues. By asking this question, you can determine whether a candidate has the soft skills for working with others. What to look for in an answer:

  • Excellent interpersonal skills
  • Example to show how they handled a similar situation
  • Teamwork skills

Example:

"At my last job, designers and electrical engineers had several discussions on functionality versus aaesthetics. While the design team wanted an aaesthetic power bank, the electrical engineers wanted a functional unit. I proposed both teams meet early in the creative process to determine how to reach our respective goals. Our solution improved the product and reduced the time both teams spent on the project."

Can you describe what an alternator and a generator are?

This technical question helps you assess a candidate's understanding of basic electrical engineering concepts. An excellent electrical engineer would explain when to use a generator over an alternator. What to look for in an answer:

  • Clear definition of an alternator and a generator
  • Understanding of when to use an alternator and a generator
  • Ability to communicate effectively

Example:

"An alternator creates energy. It uses only what's necessary and stores the rest. Unlike alternators, a generator converts power into another source. It doesn't store excess energy. In my experience, generators are good for large-scale projects, while alternators are suitable for small- to medium-scale projects."

What is the difference between alternating current and direct current?

This technical question also helps you find out whether a candidate understands electrical engineering fundamentals. What to look for in an answer:

  • Clear definition of alternating current and direct current
  • Ability to communicate effectively
  • Engagement in the idea of responding

Example:

"Alternating current and direct current both describe current flow in a circuit. In direct current, electrical charges flow in one direction, and they change directions periodically in alternating current. Alternating current is more common and safe, but a direct current is less expensive and suitable for power transmission over long distances."

How do you manage multiple project responsibilities as an electrical engineer?

The goal of this question is to understand how an electrical engineer manages their time when they need to complete several tasks. What to look for in an answer:

  • Excellent time management and organisational skills
  • Drive to meet deadlines and targets
  • Ability to work in a fast-paced environment

Example:

"I think I have excellent time management skills. I like to plan my day before starting any project, and prioritizing tasks based on their due dates is important to me. Once I have a solid plan, I try to stick to it and stay focused. I also adjust my plan whenever necessary and delegate tasks to meet deadlines. I make sure I communicate expectations and the project's progress with my supervisor and other stakeholders."

Which electrical engineering software programmes are you familiar with?

Electrical engineers use software programmes to analyse results, simulate processes, test systems, and conduct related functions. The goal of this question is to assess a candidate's electrical engineering expertise. What to look for in an answer:
