She doesn’t need an interview AT ALL to get financial aid from a CSU in Calif. Just make sure that your child has followed all the guidelines to qualify for a Cal Grant…make sure she checks with the GC at school (Guidance counselor) to make sure her GPA is submitted, etc, to qualify.
If she does all the right things with her GC to get her Cal Grant, then the CG and Pell Grant and fed student loan will cover nearly all of her costs. The CG will pay for her tuition. The Pell Grant and student loan can cover her room.
If you apply for a Plus loan and are denied, then your DD can borrow $4k more on top…but try to avoid that and have her work/save in the summer. Extra loans will be a burden later.
