Hi, so i'm assuming you're placements have been started and you wanted to know about the process.

Okay so basically you don't need a specific book for HR round. You just have to work on your communication skills.

Usually a campus placement have a screening round and HR + Technical Round. Not every company has the same but HR round is the round that you are going to face anyway.

And you just need to work on your English, confidence to clear an HR round.

The HR would ask you about yourself, your interests, your future plans etc.

I would suggest you to be a little calm while talking to a HR. My pro tip would be to make your interview more of a good conversation than an interview (figuratively speaking). What i mean is the confidence and calmness is going to help you in clearing the HR round.

And one book i think is the best for any aptitude exam and that is R.S. Aggarwal's Quantitative Aptitude. This book is the Bible for any aptitude test.

Hope this is helpful
