they reject you automatically if you have visible scars
Total rubbish. Lots of crew have visible scars, including me. The tattoo form is for identification & medical purposes. Yes tattoos can be a way of wedding people out but there are plenty of jobs which ban visible tattoos. If it's not huge and i na discreet place you shouldn't have an issue. Plenty of info about tattoos in this and past threads. I'd suggest you go read it instead of jumping to conclusions.
