The process took 2 days. I interviewed at Wipro (Bengaluru) in Mar 2012
Interview
1st round-Aptitude
It was somewhat easy and had a mixed bag of quantitative, reasoning, verbal and technical questions.
2nd round-Technical interview
Was asked about favorite subject, why that subject, etc.
3rd round-Hr interview
Was very nice and was asked basic questions about what was in my resume.
