I applied through an employee referral. The process took 4 weeks. I interviewed at ZS Associates (Pune) in Jul 2010
Interview
Quantitative Online test -> Case Study -> Technical interview -> Principal Interview.
All these steps are progressive, one has to clear the earlier rounds to get into the next. The case study round is where ZS grills the most. Rest all rounds will be more friendly discussions.

Question 1
Case stud, ZS cases are periodically updated by a panel of current employees and the quality of cases is very high. They give heavy importance to detail. Go through the case thoroughly and dont be afraid to get any clarifications from the interviewer if required.
I gave an interview for the business technology associate. Dificutly level of the interview at ZS associate was moderate. They mainly asked about the resume - related points e.g. past projects and experience at previous company.
