How many times to send out your Resume to one Co.

[bds]

I sent 3 resume got nothing,no calls 000..I want to work there I like there hours and tips.

It is a busser job. I don't want to seem needy.But the lady did say in April, they may
start hiring. I know mothers day""may""" is a Fine Dining restaurant Xmas.
