I applied through college or university. The process took 2 months. I interviewed at Cognizant (New York, NY) in Dec 2010
Interview
Easy process, not many questions, vetting process is random. You meet with a recruiter, fly to HQ, have three rounds of interview, then you get email, then contract, then all the other logistics.
Interview questions [1]
Question 1
Some questions regarding DB were unfamiliar but overall nothing was close to be difficult
