You get the feeling that this was not phishing scam with the ultimate goal of financial crime. This (to me) smells more like a specific, personal attack on this woman with the intent to humiliate and embarrass her professionally.
You either know about the "IT cell" or please google it ... all the links on it are non-authoritative.
This is exactly what it feels like to me.
Assuming the scammers are Indian, and the victim would be expecting some Americans interviewing her, I wonder how they scammers got some Americans to join in the scam. Hire some American actors and tell them it's for a prank TV show maybe?
