Interview
First round - Online Aptitude test
Second round - Case study round
Third round - Interview based on the case study
Fourth round - HR round
ZS shortlisted 15 students after the first round for the case study round. After the case study round 11 students were shortlisted for the final HR round but they took the interview of only 6 students out of 11 saying that we are done for the day and out of those 6 , 5 were selected. This shows how unprofessional the firm is. They made us sit for 7-8 hours and didn't even take the interview even after shortlisting us.

Interview
This is a 3 stage process. First, they give you a case study. Secondly, there is an interview on general topics (academics, experience) and the Case Study you did. Thirdly, there is another interview which is mostly a personality test and has questions on general topics with some quizzes and/or puzzles.
Interview questions [1]
Question 1
You have two ropes coated in an oil to help them burn. Each rope will take exactly 1 hour to burn all the way through. However, the ropes do not burn at constant rates—there are spots where they burn a little faster and spots where they burn a little slower, but it always takes 1 hour to finish the job.
With a lighter to ignite the ropes, how can you measure exactly 45 minutes?

The first round consisted of a general aptitude test which mainly consisted of Data Interpretation questions . Rest of it was relatively easy. The second round was a video round where most of the questions were guess estimates or general behavioural questions.

Good and Tough, the Interviewer was frank and helped in between if you get stuck and will provide hints for complex queries and be confident of what you say and always backup your answer.
