Packaged and canned corporate speak already happens and will continue to happen. However, assuming you are meeting face to face, you can see their faces when they do it. Generally most people's bs-detector is good enough to catch such pretending and that is the point of the questions - not only what words are coming out of the interviewers mouth but whether those are believable based on the expression/body language etc. People overrate their ability to lie convincingly.

True. Though, when they give you a corporatespeak answer to an otherwise meaningful question, the only thing you've learned (if they're not giving additional cues, like you said) is that this particular interviewer gave you a corporatespeak answer, not why they did.

They're not necessarily trying to cover up anything, like telling you some unfavorable truth, but merely trying to act corporate.

So, it's evidence in support of the suspicion that this company is full of commonplace corporate BS, but it probably doesn't even indirectly answer the more specific information you were trying to get at.
