I applied through university. The process took 1 day. I interviewed at Decathlon (Chennai) in Feb 2016
Interview
First round would be a sports round. It would not be focusing on how good are you at sport, but your will power, if you give up easily or not, if you are a team player, whether you possess leadership skills etc.
Interview questions [1]
Question 1
