I applied through college or university. The process took 3 days. I interviewed at Infosys (Pune) in Sep 2014
Interview
You have a set of 3 light switches outside a closed door. One of them controls the light inside the room. With the door closed from outside the room, you can turn the light switches on or off as many times as you would like.
You can go into the room - one time only - to see the light. You cannot see the whether the light is on or off from outside the room, nor can you change the light switches while inside the room.
No one else is in the room to help you. The room has no windows.
Based on the information above, how would you determine which of the three light switches controls the light inside the room?
Other Software Developer Interview Reviews for Infosys
L3 interview:
Pretty inefficient process, with certain people having to wait 6+ hours, and I heard of one person who waited an entire day and had to come again the next day.
Interview itself was relatively standard,
stage 1: Asking leetcode mediums and expecting optimal solution, then moving to core cs concepts like oops and sql.
stage 2: Diving into projects, with questions on the tougher side, like specifics about the architecture of docker.
