Fresh HR Graduate Seeking Interview Prep: Where Can I Find Study Materials and Guidance?

I would like to apply for HR jobs as a fresher. I have completed my MBA in HR and also have a B.E. in Computer Science. I would like to know if there are any websites where I can find the study material required for HR interviews. It would be very helpful if you could guide me on how to prepare for interviews. Please help me.

Thanks

I have done MBA in HR. Recently, I am looking for a job. Could anybody suggest some HR-related certification courses that could help me secure a good job?
