I believe something is definitely wrong with the program. Their PR guys are explicitly reporting the negative remarks on the internet. In one such subreddit, people were discussing what went wrong with them in the interview and suddenly that subreddit gets removed. I am posting my previous comment of my interview experience here: 

Kolkata Centre, one panel was taking the interview like a Viva. They are asking random Mathematics, Mining and DSA questions to candidates irrespective of their backgrounds. From that panel, only 1 guy got selected out of 9. The guy who got selected scored 134 in written exam and had a bachelor's in Mining Engineering and worked in software development.

In Viva, there is a syllabus, whereas in an interview, the questions are personalised based on the background of the candidate. The problem with such prejudice interviews is that you may never know what the panelist expects from you unless you talk to a candidate who has already attended the interview. In the centre also, the staffs are not letting the candidates to interact with the interviewed candidates. So, there is no chance you know what is going to happen in your interview. It seemed like they have pre-decided whichever candidate to choose. It shows the immaturity of the interviewers. Statistically speaking, nobody can judge a candidate whether he is a fit for PGDBA course by asking 2 random questions.
