Being a Graphic Designer in RTC requires a little bit of photography skills (taking photos for their club publication). It's alright if you don't have photography skills because they will teach you there!
The hardest part of the job is manually cutting and pasting the promotion posters (it's best to print it a week earlier so you have ample time to cut and paste the posters together). Other than that, you really have plenty of chances to hone your design skills.
You'll be expected to OT to take photos of the events (Christmas, NYE Party, etc) happening at the club (but you can discuss this with your colleague and take turns to stay). Other than that, OT-ing to do design work hardly happens, unless you're rushing for deadline.
Everyone else is nice if you do your job right and it's best to mind your own business to avoid any work politics.
