Yah, I did. They gave a series of questions beforehand and asked us to answer it then the interview was done in group of 5 (for my session).
First, requested us to do a simple introduction of yourself.
Next, the rest of the session revolves on discussing about the questions (what you answered, what do you think, why, theory behind it etc)
The questions are on basic engineering knowledge:
(i) fluid dynamics, pressure drop calculation, what factors affect pressure drop, some simple calculation on pressure drop and etc
(ii) differences between dew point, boiling point, and bubble point and some theory etc
(iii) some everyday logic such as how to describe refrigeration using mass and heat transfer, dew formation, car air conditioning etc.
I think they wanna assess basic understanding but really don't know what they are looking for in a candidate though, my friend answered very well but didnt get selected for the programme.

same goes with me... i also got rejected... i think we were in the same group back then...hehe.. u from unimap right?
