I applied through an employee referral. The process took 3 weeks. I interviewed at ZS Associates (Washington, DC) in Aug 2020
Interview
Essentially two rounds. The first round has two interviewers about one hour each - one interview is a case interview with a lot of data and slides, and the second is a behavioral interview. The final round is 3 interviews: one interview is behavioral, the second is a soft case interview (without data and slides) and the last one was a desk case interview where I was given ~20 slides and an objective to make a recommendation within an hour. I had to make slides, present them, and then answer questions from the interviewer, so in total the final round took around 4 hours.
Communication round , first it was a aptitude test round which was online. I was able to clear that one but miss the verbal communication round. The reviews I heard for the company were great and nice. Missed opportunity
Long interview process. Pleasant people to talk to. Very straightforward and reasonable. Interview was similar to many large consulting firms. Was extended and offer for an offer with a relocation package. Ultimately decided that it was not right for me at this time.
