Interpersonal skills are often called "people skills" because they describe a person's ability to interact with other people in a positive and cooperative manner. Unlike technical skills that people attend school for, interpersonal skills are considered soft skills that are typically developed over time through interactions.
Having good interpersonal skills is desired in most careers. The best members of a team often have strong skills that help them communicate and problem solve with other people in an organization. There is a long list of interpersonal skills, but among the most important for working in a team or workplace are conflict resolution, communication, problem solving and patience.
