I have a tattoo which can be hid. Personally I wouldnt care if they had a tattoo or not, as long as you can do the job.
My tattoo I designed myself. I am a woman so people over her might think its not a good look for a woman but at the same time people shouldnt judge you.
I have seen bad tattoos and good ones. One bad one I saw was on my mates hand I thought it was when you write on your hand with pen but it was not straight.
Anyway it shouldnt be a problem.
