I applied through college or university. The process took 1 day. I interviewed at Carrefour (Rājpura, Punjab) in Feb 2020
Interview
Online test
2 technical rounds
1 HR round
Online test had 3 coding questions and 6 MCQs.
Coding questions were simple DS and DP problems.
Technical round was difficult. They checked basics of OOPS and projects you've worked on.
