Moody's interview questions

My application got pushed through the first screening process, where I spoke to someone in HR. The phone interview itself was with the head of research of Moody's Analytics. It was exactly 40 min. I was asked a lot to describe the models used in my dissertation.

An initial phone interview, followed by an in person interview with 2 people from the unit I work with, followed by a take home test, followed by an in person interview with the Managing Director
