I applied through college or university. I interviewed at Infosys (Bengaluru) in Nov 2016
Interview
One online test followed by one technical and hr discussion .Online test is Average.
Interview is easy.
I joined as a fresher so mostly the questions were on my college time projects and on basics of languages I have given as preference
The hiring process had multiple rounds, with each round being more articulate than the other. Each round was an eliminating round and the questions asked were tough and direct and tested your knowledge.
I applied through an employee referral. I interviewed at Infosys
Interview
They had me take a math/stasitics test. Then after that an interview was set up about 2 hours. First hour was software questions and the second half was HR questions. If you know general software knowledge should be fine
