There are times when it is necessary to recognize that we are interacting with the environment, not in our capacity as logical problem solvers, but in our capacity as social apes.

"This presentation is bullshit. You have no evidence, nothing valuable to show, just spurious subjective opinions. You've put up a straw man and now are trying to knock it down assuming we are idiots. I've seen enough."

At this point, the correct response is "Yeah, I've seen enough too. This interview is bullshit. I'm surprised you clowns are still in business. Good day." And pick up your stuff and walk out.

Obviously that won't get you the job, but nor will anything else; in reality, as very often happens, they made their decision no later than ten seconds after you walked into the room. (Anyway, would you even want to work for people like that?) Continuing to stammer meaningless-in-context words about tech stuff will just result in damage to your self-esteem, which can have significant negative consequences in your life for years down the line.
