Being introvert or extrovert is natural personality trait. Therefore, there is no need to change it forcefully. There is no evidence that shows that extroverts have edge over introverts. You may be introvert but do not be inscrutable.
Secondly, have you taken any scientific psychological test that showed that you are introvert? Who has verified validity, reliability and credibility of the test?
Thirdly, if someone has given a feedback that you are introvert then you may develop your better networking skills. Leaders demonstrate outspokenness. Their communication is characterised by directness in manner or speech. Therefore, be communicative. When I recommend you to be communicative, please note that I do not mean to say that you need to improve communication skills. You may have good communication skills but what is the use of those skills if person does not use them? Communicativeness demands being proactive and responding to the communication in timely manner.
Fourthly, please do not mistake outspokenness with talkativeness. Chatterboxes are introverts too. What we communicate should be meaningful, to the point and with supporting examples. To make your communication meaningful, improve your listening skills as well as questioning skills. In fact if you ask questions then people will be forced to give reply. Please note that people like those who listen to them! Listening others does not mean accepting other person's views. Do not contradict or come up with counter argument instantly. Put your opposing views without offending other party.
Next thing is not being stingy with the words. Many people prefer to communicate tersely. However, terseness mars the spirit of their communication.
Lastly, people become introvert because they have nothing to say. Therefore, improve your reading. Read editorials and centre page essays of the newspaper. Discuss the contents with your friends and family members. This will improve your confidence.
All the best!

First of all, stop thinking that you are lntrovert . You increase your one to one contacts with fellow workers, listen to them and speak on work related matters.Attend to social events and participate whole heartedly . Make new friends and converse in the language you are comfortable with. Attend some professional public speaking course which will immensely help you.
Don't try to label yourself as lntrovert or extrovert.Simply think differently and act.

Further to the above comments and observations, I cannot help feeling that there is an underlying issue here.
We are all to some degree or other introverts AND extroverts, it all depends on the situation. For example, one may be an introvert at work and an extrovert at home, or vice versa.
Therefore, perhaps the question you need to ask yourself is in which situation are you an introvert and then apply the advice given by Dinesh and Vinayak above.
I hope my comments help.

On a continuam scale ,introvert and extrovert are at the extreme ends.Introverts generally are self- centred, not good mixers, are afraid of talking because of the imaginary fear of what would others think, and don't open up easily .If HR person displays this behaviour, certainly it will greatly affect his functioning unless he makes serious effort to change himself.
Again it is not black and white situation and there are shades of grey in between and also degree of difference between two individuals.
The real issue is if above or similar behavior traits are possessed by an HR person, regardless of whatever label we give it , this paradigm needs to be changed .
