Of course Yahoo will do at least similar level interviews for expensive acquihires as to their normal hires. It's a standard practice, Google does this too. They are looking to acquire people that fit to their culture and standard interviews are their procedure to try to ensure that. I'm personally of the opinion that a little bit of diversity (more designer-type front end devs without academic background) would do good for Google's (or Yahoo's) internal culture, but if they have decided that they only want CS people, it totally makes sense to interview acquihires too.
