The process took 3 weeks. I interviewed at ZS Associates in Oct 2011
Interview
Applied through campus. 1st round interview consisted of one typical behavioral and one case. The case interview related to the pharmaceutical industry and was more of an interview-led Q&A. Interviewer read a prompt, stated some data, then asked questions. More data was given and more questions asked.

I applied through university. The process took 2 days. I interviewed at ZS Associates (New Delhi) in May 2018
Interview
There were 4 rounds.
The first was an aptitude test which was held on campus(DTU)
Selected students had to report to Gurgaon Office for Case study round followed by 2 F2F Interviews.
The aptitude round was not tough, basic quant, reasoning and verbal questions.
However, the Case study was very tough. We had to write the solutions and present analysis on a separate sheet of paper within half an hour. (Try to read the entire case at least even if you don't solve them because you end up solving the entire caselet again with the interviewer.)
F2F Interviews were generic cv based questions followed by a guesstimate and a puzzle.
The last round was with Partner round. Behavioral questions, guesstimate and a puzzle was asked, lasted for more than 1.5 hours.

Question 1
I went through 3 rounds.
1st was a case study interview where in we were give a data set and 4 questions based on it. Interviewer asked what I understood from the question, my answer and my understanding of the data sets. He was helping wherever I was getting stuck and overall he looked for the approach.
2nd round was a telephonic interview where I was asked the puzzles and guesstimate. I was asked like how many tennis balls can fill an airplane. Puzzles - classic three ants at three vertices of an equilateral triangle. And another one was, there are 10 steps, you can take 1, 2 or combination of both steps at time then how many ways can you climb up. Then general questions about yourself and why ZS, you are from technical background then why analyst. The last round was with a senior manager who asked basic HR questions like why do you think you will be successful in ZS and asked me some puzzles.
