I applied through college or university. The process took 1 day. I interviewed at Publicis Sapient in Oct 2010
Interview
I did an interview through campus career services. There was an information session the day before the interview. The interview itself was 1 on 1, and consisted mostly of walking through my resume and doing personality questions. The interviewer was nice. I tried to follow up, but received no replies. I assume my application is no longer being considered.
Smooth, focused mainly on trees, arrays, dynamic programming and popular backtracking problems that can be practiced through GEEKS FOR GEEKS and other sites. I would recommend not to go after competitive programming for this company. Rather focus on diversity and basics.
