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 applied through other source. The process took 2 weeks. I interviewed at ZS Associates (Pune) in Jan 2014
Interview
I applied through their offcampus drive held in PCCOE, Pune on 14th January 2014. Exam was conducted by AMCAT nd was fairly easy. But their selection process is tough. Assuming 3000 students appeared, only 116 cleared aptitude. It was followed by a telephonic round which was more of a formality and an invite for face to face interview.
The next major elimination round was Case Study round. For BTA role, a dummy business problem was given and questions logically based on databases and SQL were asked. Very interesting. After clearing this, there were supposed to be 2 rounds -behavioral and principal but it was combined in 1 for us due to shortage of time. It included some more SQL questions, puzzles, guesstimates, resume probing questions and general HR questions like weakness & strengths.
At every stage, they will just check how smartly you approach the problem rather than the end result. Communication skills must be strong.

Very long hiring process.
1. Written test (conducted by AMCAT-fairly easy)

3. Case interview- pretty tricky round as the case is something they take very seriously.
4 2-3 HR rounds
