How long was it in the tank?
How was the tank dried after testing?

Are they the kind of people who might have sealed known leaks with silicone gunge so it would get through the hydrotest and they could get paid?
Not that any of my contractors would behave like that.

What is the coating inside?
There may still be a pool of water in the bottom.
But, if it started leaking right away then the hydro was not done correctly and the leak was there before the fuel was added.

You are judged not by what you know, but by what you can do.

All of this depends greatly on a) how high the hydrotest pressure was and b) where the leaks occurred. The OP needs to tell us these things for us to be of further help.
