Missing WCF interview questions list on Google

Probably not - "interview questions" sheets come up from time to time, and disappear into obscurity when people realize they are all rubbish.

They won't help you get a job: they will probably reduce the chances instead - because although they give you one answer (and you hope like hell that comes up but it probably won't) - but they don't give you the information you need to answer follow up questions, which will always happen.

Instead of spending time trying to find a way to answer questions that won't be asked, learn the subjects required by the job itself - and if you don't know an answer, say so. You will get much more respect than if you parrot back somebody else's answer and then show you have no idea what it means when they follow up.
