I'm curious. What would be a good reaction? Not reacting and accepting that's only truth from now on? Reacting respectfully saying why you think there are more than one answer, then continue getting pushed?
When I test people's reaction, it's generally not because I want to hire them. I just want to learn about people. If the purpose is hiring, overreacting but good coder will not take the job, under-reacting but good coder will not stay long because he/she will get angry eventually, over-reacting and taking the job seems desperate... I just don't see what can possibly get out this kind of test from a hiring perspective.
