How do you present yourself in front of others is important. How comfortable you can hand over and take over the decisions responsibilities is important. All these are the part of the personality.
The recruiter needs these qualities. All these qualities you have to convey to the recruiter through the resume. Now this does not mean that you have to mention them point wise in the resume. The experience you write must speak out these to the customer. He must feel like you have an impressing personality. Because, the person with good personality will make him earn more profit rather than the person with good marks. If there are 2 different persons in front of the recruiter and he has the choice to appoint any one of them. If one of them has good academic records but does not have good personality. But the other one is the average scorer but with good personality. He can easily implement his ideas.
The recruiter will surely appoint the person who has the good personality. Because, if the person with good personality can be given some sort of training to increase his knowledge level but the person with good score what sort of personality he must be given. Personality depends on your nature. This is the importance of having good personality.
Professional resume is all about conveying all your qualities to recruiter through the content you write in the resume.
