What are the expected questions of HR round?

In this round, some HR asked very common questions while some takes this round as a technical one. But I am sharing some very common questions that may be asked in the HR round:
·         Tell me about yourself?
·         What is your knowledge about IBM?
·         Why you want to join IBM?
·         Give one reason to hire you?
·         If we hire you then how you have contribute to your project?
·         Do you have any questions?
These are the sample kind of questions. You can prepare them but do not restrict your preparation with these questions.
