I applied through college or university. The process took 2+ months. I interviewed at ZS Associates (Pune) in Aug 2016
Interview
The interview process starts with a given case study. You have to basically find solutions for the problems mentioned. Then your first interview is based on these case studies only. After the case study they select for a behavoiral interview. The most pathetic thing about ZS interviews is that if they found their ideal candidate in first 10-15 interviews then they won't even bother to take your interview. Then it's just for the sake of formality they'll take your interview and they definitely won't take you to the next round. Never seen such policies in interviews before. Most worthless interview ever.
Interview questions [1]
Question 1
Which database you used in your projects? And queries on JOINS, TRIGGERS ,VIEWS.
Lengthy and time consuming but process is very good nothing casual and systematic I cleared 3 rounds and in the last round I didn't get positive feedback. So process was nice but we can't say how they judge you even in the last round and reject you.
