Sanjib, are these resumes formatted in a manner that a computer program can easily find the data that is needed or are they formatted for only people to understand? The data is probably not formatted in a manner that can easily be obtained by a computer program. Regardless, you will get better help if you create a new thread (discussion) and explain your specific problem better.
The data probably must be processed by people; a data entry type of person that specializes in that. You can probably write a program that can get some of the data automatically. I might have more suggestions but please start a new thread for that.
Thinking is a feeling; pleasant for some and unpleasant for others.
