Ganesh, I am in this industry from last 12 years. And worst part is - every resume is written in different format. And these formats keep changing with new batch coming in.
I seen only few companies are there in world, And my last working with Infosys and Wipro, even they are using 3rd party tool for resume parsing.
I recommend
www.rchilli.com as we used them in our corporate website and working perfect.
