"Maintenance technicians are responsible for resolving problems with equipment and systems in their respective fields. Experience and technical knowledge of your field are key for impressing employers during an interview, during which you will be presented with hypothetical questions about common issues and inquiries about past problems you have resolved. Various maintenance careers require different levels of education and certification."
The Practice teach is the hardest to prepare for. You must be comfortable with a presentation that you will have to create for yourself. You will be giving that presentation to a group of maintenance instructors. It is most important to be well practiced in what words you will say, and to be completely familiar with your presentation.
