An interview is what an individual should prepare for,
Always make an inquiry to know what the company produce, try to meet some staff and asked... them about some likely questions, some concerns they have in the company, this will aid your preparation. Practice answering some questions on your own before the interview day. more

In addition to what @Erin just said, practice this:
Do a video of yourself partaking in the interview, like, get a chair, sit and place your phone in... front of you and start speaking, then watch yourself as you're doing it.
Practice it till you are tired.
It will help you a lot more

An interview is easy cause it’s all about learning you, so you are the only one who has all the answers! Yes, it can be a little intimidating at... first, especially on panel style interviews, but take a breath and remember they are just people too. Also, rub a little deodorant on your hands before walking in to assist with the sweaty hands. Good luck! more
