How to seem genuine in an interview?

Hi all,

I'm currently interviewing for roles and I'm having trouble coming across as genuine when I give my cookie cutter answers. I think its a combination of nerves along with the fact that I'm inexperienced with interviews. Based on your experience, what's the best way to showcase personality yet remain humble and show that you have a good understanding of how important it is to fit in.

Need some pointers on how I can seem more genuine moving forward and I'm open to anything you guys have to say!

Thanks
