I applied through college or university. The process took 2 weeks. I interviewed at ZS Associates (New Delhi) in Jul 2019
Interview
The first round was an online round which comprised of aptitude and video interview. Students could take the test from any place. The interview was accessible only for those candidates who scored well in aptitude round.
After the results were declared for the first round the second round consists of case study round. The case study for a BTA candidate was related to statistical topics. The questions comprised of data analysis and SQL Queries. Based on the case study, there is a case study interview. In the interview, the interviewer asked questions related to case study and SQL Queries. I performed well, but the interviewer found out that I was not interested in data analysis job based on my resume as I had nothing related to data analysis, and SQL was missing from my resume (major blunder). So prepare your resume accordingly. I had no regret on being not selected, as anyways I didn't want to write queries for the rest of my life.
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.
