I applied through college or university. I interviewed at ZS Associates (Pune) in Jul 2019
Interview
There were 3 rounds:
1st Round - Case Study (Data Heavy)
There were 8-10 pages describing the case containing 4 questions with a time limit of 30min.
After 30minutes first f2f interview starts where the case study is discussed.
2nd Round Technical
Various guestimates, puzzles, small case study, product launching strategies were asked.
3rd Round - HR & Tech
The questions asked in this round were to establish whether you are fit for the company.
Interview questions [1]
Question 1
Why ZS?(Being from an engineering background)
Why consulting?
What if you are not selected today?
Case study round was interesting- there was a lot of extra information to confuse you but at the end it is basics you have to focus on. Technical and HR round was not too difficult.
I applied through college or university. I interviewed at ZS Associates (Chennai) in Sep 2022
Interview
The hiring was done at a bschool, hence for offcampus the process might differ. After initial screening, a submission had to be done through a hackathon(business case). Post that, the shortlisted students had two interviews- first being a thorough case discussion, guestimate and second being mixture of puzzle, behavioural questions, work ex related ques and guestimates.
