If you are a fresher, then it is important for you to understand how the business functions. What are the important processes and how to improve customer satisfaction. Identify various costs associated with your business and find out what as a HR you can do to reduce the costs.
What I have written above, if you find it to be too difficult to do then you may take the traditional HR role of establishing proper HR systems and processes. Most important in this segment is properly measuring the performance of the people. This is also no insignificant task. Even to do this also, you would need guidance. Identifying competencies for the job or competency mapping may sound fancy however, it is too early for you to get into this.
Surf this forum for the various challenges that members of this forum have posted. Imagine if the same challenge if you were to face then are you capable to handle it or how you would have handled it differently. This is also a great work if you wish to do.
