In order to interview for a position as an electrician, you must have completed the necessary professional training and technical education. You will have likely trained to one of three levels: apprentice, journeyman, or master electrician.

While your job application and resume reflect your experience, you need to be prepared to discuss your qualifications in depth during the interview process. To prepare, review and practice with this list.

Common Electrician Interview Questions

Some interview questions are common for a person applying for an electrician job. If this is your first job, run your answers by a seasoned professional who can help craft your responses. Some of the questions are more generalized:

  • How many years have you been working in the industry?
  • How and where did you receive your training?
  • What was a time when you had a problem you could not figure out and you had to find a solution on your own?
  • Could you describe some recent projects you have worked on, in detail?
  • What does a fuse or breaker do? What are the differences between the two?
  • Can you describe the electrical systems you have worked on and are most familiar with?
  • Do you specialize in any specific areas of electrical work?
  • What do you do to protect yourself from electrical accidents or injuries?

    Technical Questions

    Often during the process, if you have made it past the initial inquiries, the interviewer will throw in some technical questions. Winging it through these types of questions is difficult, so be prepared:

    • If you were in a room with three light switches and the room next door had three lightbulbs, how would you find out which three switches controlled the three bulbs if you could only go in the next room once?
    • What does "PPE" stand for? How important is safety on the job?
    • What is CSA approval?
    • What does "14-2" mean?

    Make sure that you can answer these types of questions with confidence, using your answers to highlight what sets you apart as a candidate. Remember that how you answer interview questions can be just as important as the answers themselves. 

    A Note on Dress Code

    As a trained electrician, you know that working conditions for electricians vary depending on your specialization. For most electricians, the work is physically demanding. Occasionally you must work in a tight space, having to bend, squat, or kneel to make connections in awkward locations. Industrial electricians may find themselves in the heat, dust, and noise of an industrial plant. Your typical work attire likely suits your everyday work, but it won't suit an interview. You want to present yourself as the professional you are.

    The typical advice for trade job interview attire is to go business casual, so leave the jeans and work boots at home. For men, business casual might mean a nice pair of slacks, a buttoned shirt, and clean, polished shoes. For women, slacks and a professional business top are advisable. This is not a time for a formal suit, but do present yourself as organized and with an attention to detail. Your interviewer will notice and assume that you put the same care into your work.

    General Job Interview Questions

    In addition to job-specific interview questions, you will also be asked more general questions about your employment history, education, strengths, weaknesses, achievements, goals, and plans. Although these questions are usually used as a warm-up, it is good practice to have the right answers memorized so that you can focus on the more technical question when they arise.
