William Swansen has worked in the employment assistance realm since 2007. He is an author, job search strategist, and career advisor who helps individuals worldwide and in various professions to find their ideal careers.

While knowing how to design electronic hardware is the key competency of a senior hardware engineer, knowing the theory behind the design and how each of the functions of the components is critical. This provides the engineer with the information they need to quickly develop designs that will function as intended. Interviewers at Cisco will ask you about theoretical situations, practical aspects of your job, and real-life scenarios you will likely encounter once hired. Anticipating these and preparing your answers in advance will help you perform well during the interview with Cisco.

William Swansen

"A circuit stores an electrical charge using capacitors. Capacitors come in several different ratings and can store electrical charges for designated periods. The storage mechanism within the capacitor is similar to that of a battery, except capacitors use electrostatic fields between their conductors instead of chemicals. When another device activates a capacitor, it releases the energy into the circuit."
