One of the following, Wife, Girlfriend, Kids.
It's a self-esteem issue. When a big moment occurs, you become far more self-aware. When it doesn't. Stuff still happens, you are just far less self-aware because you aren't doing any healthy self-inspection before a big date.
I found relaxing makes the entire process much easier and you connect easier with the employer. If you know the job, then just let the questions come. Take them in stride. When you worry, you become less natural and you are less likely to have a good interview. If you aren't a fit for the job, don't interview for it. You're wasting your time and theirs. If you get hired, you will be fired or put in a position that you will not like.
If I catch someone lying on their resume, that is an immediate no go for me. I won't hire liars if I can help it. Apply for jobs you can do. If you want a job you can't do. Train for it and practice. Learn whatever you can. Then let the employer know this is what you want to do. Never lie about something you know nothing about. You will be exposed for what you are. A liar and your future at that company is doomed one way or another.
