I applied through college or university. The process took 1 week. I interviewed at ZS Associates in Feb 2015
Interview
There were two 30 minute interviews. The first one was fit. I don't recall anything being too difficult there, but I remember it ended quite short of the 30 minute mark. The case was extremely hard. There were very confusing charts with weird numbers that I haven't seen before. The case was about introducing a new product and how to analyze the data for it. The interviewer was really nice and wanted me to get it right but I couldn't really get through it. Overall people seemed really nice at the company.

Question 1
Asked to interpret numbers on a very difficult chart. Not simple profit/loss calculations but had concepts nestled inside other concepts.
I applied through the company website, and about a month later the HR reached out to schedule a phone interview. The interview lasted only around 10 minutes, and two days afterward I was informed that I had been rejected.
Very straightforward process, 1 round of case + a final round of 1 behavioral, 1 structured case, and 1 unstructured case.
I'd recommend brushing up on your brainstorming skills and quick math.

I have only gone through the first-round interview, which was a recorded video format. The interview consisted of three behavioral-based questions, where I was given three minutes to think and prepare my response before recording my answer. Each response had a time limit of two minutes. There was no live interaction with an interviewer, and the entire process was automated.
