Are all the tiger tanks meant to be used as snipers?

It's hard not to feel like you're an invincible force as a German tiger but from a lot of the posts I've read, the tigers are meant to be played back and snipe for the most part. Is this true and does anyone have any advice on how to do well with a sniping playstyle in a tiger? (Tiger 1, tiger 2, jagdtiger). In higher battle ratings, I can play hull down and also stay behind a hill and pop out but I feel like with a tiger, it would be hard to do that so what should I be looking to do in a battle?
