The waiting time was longer than the actual interviewing. Think the interview was less than 15 min? If you don't have questions to ask, will be even shorter.
Seems like for PT programmes, they just want to be sure, and want you to be sure, that you are serious about taking up this course, and are ready to take up the challenge.
From what I remember, the prof asked what I think BA is, and why I chose this course, then briefed through the programme and curriculum structure. Told me what's to be expected, what challenges student face, and gave some advice. I asked about the employability upon completion, and wonder if their graduates end up working in related fields, which he tried to answer to the best of his knowledge.
Hope this helps
Did they asked technical questions like how can you apply BA or analytics-related questions during the interview?
Was the process same as the FT one? Eg essay, quiz etc
