Publicis Sapient interview questions

I got a call from the recruiter, and he scheduled an F2F. At the interview location, I was given a pen, paper, bottled water and coffee. I was given a case study and was requested to design a system that would improve ABC company's processes. It also included making a project plan. I finished both in two hours. Interviewers went through my solution and the plan. There were two subsequent interviews, one technical and one managerial. The interviewers and the recruiter were very polite, made sure I was always in a positive mindset, and gave frequent feedback. I got the offer the very next day. Even after the offer, I received many phone calls from the recruiter and one of the interviewers for the orientation of the company, my job profile, growth plans etc. I had around 15-20 interviews in these 2-3 months of period with several other companies, but I have to admit, Sapient was the best amongst all in terms of manners, professionalism, scheduling and everything else. I wish them success and excellent future.
