Who do you imagine would be the user that would bother going through this interview process? If you've used the site before you already know how strict the moderation is on questions keeping people from asking questions already, do you really want to add a process where the user has to kiss up to the moderators for a couple weeks before asking their question as well?

It just would not be worth any new users time, especially given that when a user wants a question answered, it tends be slightly time sensitive.
