Electrician Interview Questions
Electricians are the people you call when you have an electrical problem or want to install an electrical system. Hiring for one can be tricky since, apart from theoretical knowledge, you need people who respect safety precautions, work well in teams and possess an analytical mind.
Requirements will vary depending on whether you’re hiring for an apprentice, a journeyman electrician or a master electrician. Apprentices should be motivated and able to follow instructions to the letter. With other candidates, ask questions to determine the level of their technical expertise and ability to solve problems. Master electricians also need leadership skills and knowledge of regulations and processes (e.g. acquiring permits or building codes).
Role specific questions should be tailored according to the industry you operate in. For example, someone working in an industrial setting may need a different skillset than one who works as a service electrician. Additionally, electricians employed by construction companies will need specialized knowledge such as installing complete electrical systems from scratch. The following questions provide examples on how to assess candidates effectively.
