First you need to practice infront of mirror that will helps you so much and
Don't give up just keep practice practice everyday

Take a deep long breathe, practice basic questions that can be asked, wear something comfortable and yeah don't let the fear come to your face

Start masturbating in front of the interviewer, it helped me

First, you need to build up your confidence and overcome your stage fright. YouTube got plenty of vids on these things so definitely use that. Drink water before speaking anything so that you don't have to catch up on your breath. Practice in front of the mirror each day.

Breathe in and breathe out.
Remember that the rest of them are just like you.
Normal humans.
Don't try to do something out of the ordinary. Be yourself and believe that you can do it.

if u need to get out of fear, then u need to face it first..so, first attend few interviews without much expectation about results..just go and attend..do answer what u thought without any second thoughts..more than ur answer, how u present it is what makes u impressive to interviewer..

Convince or confuse interviewer

Keep in mind that the interviewer isn't any genius either
He/she is an employee too and they know how we do
We only have to ensure that we're confident enough to learning and executing
Once a person said in this corporate world,you should be 'selling' yourself showcasing your features like they do for a "product"

Do yoh wear glasses?

Only remember , you can ....👍👍
