In contrast I did mention pprune (amongst several other sources of information). All I did was follow it up with that sometimes you need to take things on the internet with a pinch of salt, but there's lots of info on here - not just tips for the interviews/application process... see all the other threads in this particular forum, for example.
Say whatever you think is right at the time, but ultimately, be honest - the interviewers can (and will) catch you out if you're not.
Good luck!
