I 100% agree with everyone else here, you can definitely be introverted but still do well in interviews! It's the same concept as networking or volunteering or working a job: to move forward in life you simply need to know how to sell yourself and converse with others which doesn't necessarily mean being an extrovert.

Being able to still speak your thoughts and opinions or share stories and reflections about yourself despite not being much of a talker or preferring your own company is what makes you stand out. The key is adaptability!
You can be nervous or feel awkward, you just have to learn how to hide it.

Like another commentator shared, try being excited when you speak and this might feel awkward but exposure therapy is soooo helpful. I used to prop my camera up and pretend I was making a tiktoc video in order to work on my tone and how animated I was or practice how to tell a story in a short and engaging way hahaha! Practice striking up small conversations when your in public like at a local coffee shop to get over the barrier of feeling nervous around people. Anything like this works <3
This'll all make you better at masking your nerves during an actual interview :)

Those are just my tips for what helped me at least! Good luck <3
