Interpersonal skills, also known as people skills or emotional intelligence, are related to the way you communicate and interact with others. They will help you not only in your everyday life but also in your professional environment.
Many jobs involve collaboration and interaction with different types of people, and interpersonal skills are vital to make this happen. For any job even a technical one, you might need to interact with colleagues or clients regularly, often sharing complicated information or having to listen carefully to requirements. Having excellent technical capabilities on your resume won’t necessarily be enough to get you the job.
