How can I convince someone to give me a chance
Offer to work a day or 2 for free. Promote yourself. Better yet, go to the interview with your personal remote in hand to demonstrate your remote control programming capabilities. Show 'cool stuff' . Show something unique and different - not just plain vanilla. If your prospective employer seems interested, offer him/her to see the truely custom/professional/expert installation on your own system. Simply asking for a job just ain't going to cut it.
