Is this the first time that you are facing something like this? If so it is important that you apply for each role as a different entity. As you will progress in your Human resource career you will come across several applications including cover letters and CVs that is like a general thing which fits all bills. Keep in mind the company in which you are applying and also thing about whom you are addressing the application to. Read the details of vacancy clearly. Fill in the necessary details well. You should have a direct approach.
The importance of having good networking:
Networking helps a lot, be it in HR jobs or any other job. Networking can give a great boost to your career. It also demarcates people into two divisions - those who have good networks and those who don't. People with good networking always are in a better position. Many people have inhibitions about using their contacts. People tend to talk about them. But this should not deter you from using all your contacts effectively. People do require a little push in the beginning of their careers so that they can flourish as time passes by. Those who make an issue out of this are nothing but jealous. Don't pay much heed to the grapevine talks. Had they been in your place they would have done the same.
Facing the interviewer?
When you are face to face with the interviewer convey to him how clear you are with your career goals are. Not only are you seeking that particular post for which you have applied, you also are clear enough about the long term goals of your career. You have to convince him about the clarity of your vision. You must tell him that your career dreams are all achievable and you are going to achieve them with your hard work. You have to prove how worthy you are and that the company will benefit from you.
Even if you are a fresher, you must have learnt a good deal from the human resource internships that you have been a part of. Don't panic when you apply in a company even if the application is too demanding. Start from the grassroots. Know that in order to convince the employer you should first be aware of your own potentials, your career goals (both long term and short term). Be optimistic and expect the job to come about. If you follow these vital details along with proper human resource training you will not find any difficulty in grabbing a job for yourself.
