Human behavior is influenced by both internal and external factors. It can be defined as the actions of an organism in response to its environment or stimuli. Key factors that affect human behavior include the current situation, environment, history, perspective, culture, emotions, hormones, and genetics. Behavioral testing assesses areas like technical skills, leadership, problem solving, communication, and interpersonal skills through interviews and other methods. Interviews can be structured or unstructured and ask situational, behavioral, or job-related questions to evaluate candidates. Employee dissatisfaction can be expressed through exit, voice, neglect, or loyalty responses.
