Bitter truth
Those engineers are unemployable. cognizant have done a mass charity after a few years 95% of them will look out for a job change.
Companies like this are just doing charity work for us, honestly speaking.
If you ask them to write simple data structures programs and ask them space time complexity of a for loop they won't be able to answer them. Nobody has told them to join cognizant tcs Wipro Infosys etc... if you have talent then crack the open interview and walk-ins and get a job.
After taking 500+ interviews this is my option for the freshers job Market.
