If the interviewer is rude to me, should I ignore it?

The simple answer is yes, but of course this is a complex issue. First of all, you need to be sure the rudeness was intended. We all say things that get misunderstood, especially when we are out of context. Second, do you need to do anything about it? If an construction interviewer is rude to you, do you really want to work for them? Your best choice is to move through the construction interview and walk away.
