This is a good opportunity to showcase some of the more complex jobs you have completed.
Be sure to talk about the steps you have taken while completing a job such as this.
If you have not completed a job such as this one you can certainly say that but perhaps you could offer your opinion on how you would do it, if given the opportunity.
For example, if you have installed PEX plumbing in a concrete floor: "I have had the opportunity to install PEX plumbing in a concrete floor a few times in my career. It can be challenging and the best tip I have learned for a job like this is to create a plan for any plumbing supply or drainage piping which may interfere with PEX tubing layout."
If you have not installed PEX plumbing in a concrete floor: "I have not had the opportunity to install PEX plumbing in a concrete floor however I have watched many tutorials on how to properly do it. I think with some minimal guidance that I could most definitely take on a challenge like that."
