If u wanna tattoo, pls tattoo a place where your formal working shirt can cover. Eg; shoulder and back. Many big companies don't hire staff with visible tattoo coz it affects the company's image especially jobs that require u to meet clients and customers. My friend who just interview for a salesman job selling international brand product was rejected coz he's hand (wrist area) got tattoo. To be on the safe side, please tattoo a place which u can really cover.
