I applied online. The process took 2 months. I interviewed at Publicis Sapient (Chicago, IL)
Interview
Basically you meet with a few people to see if you are a fit, then do a case study. The study is kind of open ended and can suck you in. You will not have enough time to complete it. If you do, you are not thinking about everything correctly.
Interview questions [1]
Question 1
Case study came with 6 questions about risk, time, build a schedule, ect.
