1) The BA FAQs state that no tattoos should be visible and specifically notes tattoos on necks and forearms. I have a tattoo on my forearm which is not visible with long sleeve shirts - would this be an issue? I can stretch without the shirt sleeve riding up so it remains non-visible.
I can answer this one; last year at BA HQ we were simply asked "do you have any visible tattoos?" I would suggest as long as you do not consider them to EVER be visible at work you'd be safe answering "no" to this question.
If only the rest of the assessment were so easy!
