Electrical Engineer Interview Questions
Electrical engineers develop and test electronic products and systems for a wide range of projects, from small-scale (e.g. household devices) to large-scale (e.g. electrical power systems).They design and manufacture electrical equipment for use across many sectors.
Electrical engineers are involved in projects from the concept and detail of the design through to implementation, testing and handover. They may also be involved in maintenance programmes. As well as having technical knowledge, electrical engineers need to be able to project manage and multitask. They also need to have commercial awareness. Additional attributes, such as team leadership or management skills, are required as careers progress.
