Eagle is a popular software tool used by electrical engineers to design circuit boards (PCBs). Think of it like a digital drawing board where engineers can plan out all the electronic components and connections that go into devices like smartphones, computers, or any electronic product. It's part of a larger software package called Autodesk Eagle (formerly CadSoft Eagle). When you see Eagle mentioned in a resume, it typically means the candidate has experience in designing and laying out electronic circuit boards. It's similar to other tools like Altium Designer or KiCad, but Eagle is particularly well-known because it has both professional and hobbyist versions.
Designed complex multi-layer circuit boards using Eagle CAD software
Created and maintained component libraries in Eagle for company-wide use
Reduced production costs by optimizing Eagle PCB layouts
Developed prototype electronics using Eagle and EAGLE PCB
Typical job title: "PCB Designers"

Q: How would you approach designing a complex multi-layer PCB in Eagle?
Expected Answer: A senior designer should discuss planning component placement, signal integrity considerations, power distribution, thermal management, and manufacturing constraints. They should mention the importance of proper layer stackup and design rule checks.
Q: How do you manage component libraries in Eagle for team projects?
Expected Answer: Should explain library organization strategies, version control practices, component verification processes, and methods for maintaining consistent standards across team members.
Q: What considerations do you take into account when laying out a PCB in Eagle?
Expected Answer: Should mention component spacing, trace width calculations, ground plane design, and basic EMI/EMC considerations. Should also discuss manufacturing limitations and cost factors.
Q: How do you create custom components in Eagle?
Expected Answer: Should be able to explain the process of creating schematic symbols and PCB footprints, including proper dimensioning and pin mapping.
Q: What's the difference between a schematic and a board layout in Eagle?
Expected Answer: Should explain that schematics show the logical connections between components, while board layouts show the physical placement and routing on the actual PCB.
Q: How do you perform a Design Rule Check in Eagle?
Expected Answer: Should describe the basic process of running DRC, understanding common error messages, and making corrections to meet manufacturing requirements.
