I applied through college or university. The process took 3 months. I interviewed at ZS Associates in Mar 2017
Interview
First there's shortlisting on the basis of GD.
Then case round booklet is to be solved within 30 mins.
After this all candidates who have appeared in the case round are filtered from two back to back interviews namely the case interview round n EBI Round.
If they feel the need they ll also have a fit round to check the appropriateness of the candidates for the job.
