It was as you said but I talked with just two people, a pilot/instructor and an hr person, not three.
Other than that the conversation went as you described. Quite a bit of overlap with my initial interview too (why tui, why mpl, tell us about yourself,... More basic interviewing stuff) but also a couple of questions that surprised me.
For instance the pilot guy asked whether I thought the program was safe and if the candidates would have the same qualifications as someone who did it the old fashioned way or someone who has a cpl and 3000 hours to his name.
All in all it went well (I think), I should know if I'm accepted or not somewhere next week.
