Infosys Associate Consultant interview questions

They shortlisted people and took no ex Infoscian. A technical interview was conducted for the shortlisted people followed by a hr interview which is a salary negotiation round. I have 3 years of experience in IT but still I was asked questions from my second year of engineering. Though I managed to answer but it was weird as nothing was asked from my work experience and MBA curriculum.

initial screening,1st round & 2nd round of interview technical and functional. 3rd round HR.
