Interpersonal Skills:
A person’s ability to interact with others in the business domain; the term generally refers to an employee’s ability to get along with others while getting the job done. Interpersonal skills include everything from communication and listening skills to attitude and demeanor. Good interpersonal skills are a prerequisite for many positions in an organization. People who have worked on developing strong interpersonal skills are usually more successful in both their professional and personal lives. Employers often seek to hire staff with “strong interpersonal skills.”
Interpersonal skills are also sometimes referred to as social skills, people skills, soft skills, communication skills, or life skills.

Intra-personal Skills:
Intra-personal skills deal with the emotions, feelings, and thoughts that are stirred up within an individual, which the person next to them might not even be aware of. The following intra-personal aspects play an important role in our personal and professional lives:
• Self Esteem
• Self Confidence
• Assertiveness
• Dealing with negative emotions

The main difference between interpersonal and intrapersonal is that interpersonal happens between two or more people, whereas intrapersonal happens within one’s own inner self. The balance of both makes a human mature, more interactive, and a quick decision-maker.
