I am pretty new to this job as a KJ,
I started out on my own, bought all of my equipment and software.
Took suggestions from the public. Then I got hired on!
It has been great ever since.
As a KJ (Karaoke Dj) I am tasked with build up and breakdown of my station. Keep a crowd of people well entertained. Make sure all my software is up to date and paid. Keep all equipment functioning. Advertise bar specials and to tip your bar tender. I did this unpaid for free until the company was bought out and then they hired me!
