I’ve been in quite a few bridge positions.
During the interviews,
I always tell the managers
that I do NOT want a full time job
and that they would do better to hire
someone who may be interested in one.
The managers all insisted
that they didn’t want to hire the contractor (me).
The managers also all ended up
offering me the full time job
(and being unhappy because I wasn’t interested).
People (including yourself) are lazy.
Once you find a great employee,
you’ll want to hire them.
Use this opportunity
to try out a prospective employee
on contract.
Don’t promise a full time position
but
do ensure that they WOULD consider one.
Keep that possibility open.
