What can I do to make myself a better candidate?
Be sure to highlight any relevant training such as trade school experience, construction experience, or mechanical knowledge during your interview. Completing certifications such as OSHA 10 or 30 are helpful, but do not guarantee you a better ranking. The IUEC is a highly-skilled, highly-collaborative trade where a huge variety of abilities are needed. Highlight your capability to work well with others, follow direction, and your desire to learn new skills.
If you do not have access to outside training, try finding a project you can work on where you build or fix something. Being able to highlight your troubleshooting process, problem solving skills, or mechanical ability will help you to stand out.
