mostly just to clarify some items on your resume, to make sure you do have the required skills qualifications etc. Also by talking to you they can feel whether you can do basic comminucations. They'll ask a few general behavior questions. My suggestion is go to library and borrow a few books on this subject. Read some and you'll know much better. But most importantly, read your resume again and make sure you can explain everything you put there.

not necessarily the HR. A few times I got such calls with both the hiring manager and HR on the other end of the line. It was much easier talking to the hiring manager about technical stuff than behavior stuff with the HR. I totally agree with everything you said.
