Hiring Former Interns vs New Grads

Hello everyone,

I am just wondering from all of you guys' experience:

If a candidate has multiple internships with the company they are applying for, does that provide more leverage for them in salary/benefits negotiations? If so, how much more could one expect to ask for compared to the average new grad salary of that field?

I'm curious about this for any field, really, but I'm wondering if this may apply for my 2 land development internships I've had for a company. One of my managers seems very eager to have me back, and mentions it whenever we discuss a topic tangentially related to me going back to school.

I also thoroughly enjoy this field and would love to work for this company after school.

Thoughts?
