Abstract: In some examples, a controller may determine, from among a plurality of energy storage units, a first energy storage unit having a higher than median charge and a second energy storage unit having a lower than median charge. The controller may connect the first energy storage unit to a resonant circuit to transfer energy from the first energy storage unit to the resonant circuit. The controller may then disconnect the first energy storage unit from the resonant circuit, and connect the second energy storage unit to the resonant circuit to transfer energy from the resonant circuit to the second energy storage unit to at least partially balance a charge difference between the first energy storage unit and the second energy storage unit.

Abstract: Described are methods and systems for interview competency and question validation and analysis to improve the effectiveness of evaluation campaigns. In one method, processing logic of an interview design program, hosted by a digital evaluation platform, receives a request from a first device to create a digital interview for a position. The interview design program sends a list of competencies associated with the position and receives a selection of a set of desired competencies. The interview design program determines a list of questions that differentiate candidates within the desired competencies, ranks the list of questions by importance, and sends the list of questions and the ranking information to the first device and receives a selection of a set of desired questions. The interview design program creates the digital interview with the set of desired questions. The digital evaluation platform presents the digital interview to a candidate on a second device.
