Personally, I think this is good! You can show that you are different, but if you meet someone who is uncomfortable and disrespectful when looking at a double-sided resume, but doesn't want to ask you why! If you want to see his face, you can explain the reasons yourself, for example, "Someone who is curious to see my resume will ask me, why do you use both sides?" ............... "The reason behind this needs you to say it yourself, according to your own meaning.

It is certainly acceptable if you are a visionary boss, because if such a person works in this company, it will be a great wealth!

There is no good or bad thing, just do what you think is right! I wish you a successful interview!
