I'm still getting input from casting directors and some agents that want Rob Actis and myself to emphasize in our VO BootCamp Workshop for VO artists that there a lot o lot of talented people that seem unaware that people hire people they are really comfortable with.
Some Issues:
Do you dress nicely but casually? Don't go to a VO session in a suit and tie.
Be well rehearsed ! You aren't there to do your homework on other peoples time.
Remember to stay 8 to 10 inches from the mic.
Don't debate any direction you're given. Just say "OK, let me try that for you".
Thank everyone on your way out
Enjoy yourself don't look like you're struggling.
