I applied through college or university. The process took 1 day. I interviewed at Infosys in May 2009
Interview
Career Fair at the university. Short-listed based on a aptitude test. The test had two sections. Verbal and quantitative aptitude.
After that, was interviewed for 30-minutes. The interview mostly consisted of puzzles and basic behavioral questions such as tell me about yourself or why would I want to work for Infosys.
The same day I was offered a position.
