Hi, I'm new to this as well, I am going to be doing this sometime this year. I don't know very much about it but I do know that:
1) it is usually a seven-member panel that conducts the interviews
2) they will summon you and you show up - and if you don't show up, your application is void
3) it is only conducted in Greek
4) some people are not required to do this, even though they are non-EU citizens married to Greeks (just lucky, I guess)
If I find out anything more, I'll add it... but from what I hear, the aim is determine if the marriage is a real one or just for the papers, so you have to answer personal questions about each other.
