Look for whether the interviewer has added new evidence or simply challenged the conclusion. New facts that weaken your logic are a reason to update; repeated questioning without new facts may be pressure testing.

You can clarify the challenge by restating your reasoning and asking whether there is a specific assumption they want you to reconsider.

Good performance is neither stubbornness nor instant surrender. Change when the evidence changes.

new evidence = change. same pushback = maybe defend.

I ask myself if anything factual actually changed.
