Best thing you can do is research the role and see what you will be doing and what's important about what you do as a channel manager and then think how your current skills are transferable, working as a customer service rep for BT would show you have experience in customer support etc pretty obvious really. If you don't have any relevant experience I'd mention your qualities and key skills that would be used in the role. I hate applying for jobs me, you go through all the prep and you're up against 300 others to stack shelves.
I could probably learn so much there, and I think I could be very good at the job aswell.
Base79 or ChannelFlip I'd guess.
