Hi guys, if you’re half decided and still hesitant about a position, when is it the time to communicate the acceptance or rejection? Is it usually when the HR verbally offer you or after the verbal offer when they come back with the LOA? Would it be totally rude to reject signing the LOA at that stage?

It also seems like the verbal offer is not 100% exactly what they will offer in the LOA.

Appreciate any comments, thanks
