Dear Nitin,
Greetings!!!!!
It is almost impossible to write off automation for any activity, especially now a days.
However, such solutions work best where the resume inflow is too much to handle, particularly, in large companies with ever incensing need of manpower. They simply can't do without automation.
But, it is also a fact that such automation will only take care of operational details. Automation can hardly take care of the "finding right fit" aspect of hiring. For that to do, you will have to make an intelligent software involving great deal of study on current hiring practices, salary levels, human psychology & organizational culture. In my opinion, only Google is capable of making something as intelligent as that and you are probably not aiming at that.
To be precise, the automated resume screening software are already in market and if you could improvise a little bit on that , you acn definitely find takers in big organizations. SMEs and placement consultants will normally shy away because it would mean a new cost center which is always painful to add.
