Untucked Shirt With Blazer Job Interview Fashion...shirt Tucked In Or Untucked?

Job interview fashion...shirt tucked in or untucked? - untucked shirt with blazer

I have a blazer / jacket and pants color that goes with it. Then go, a button-shirt under the jacket. Should I hide the button down shirt or untucked? It seems much better untucked but I do not want to appear in bad taste.
