Reading blueprints is a fundamental skill for cement masons. The interviewer wants to hear that you have this skill and that reading blueprints will not be an issue if they hire you. Masonry focuses on specific parts of a blueprint since it deals only with structures made from units bound together with mortar, such as stone, bricks, glass and concrete blocks, and tile. You do not necessarily need to learn how to read the entire blueprint, but it is best to learn as much as you can for your profession. Describe your experience reading blueprints and explain where you learned how to read them.
