Engineering definitely helps your job prospects.
That's over 108k in loans and it'll likely be higher because your tuition will increase. That's certainly not as high as it COULD be, but it's not really low, either. What other options do you have?
My other option is UC Davis with a COA at $46k/year. Also, I'm waitlisted at UC Irvine which could be an option if they decide to make an offer with $$.
By the way, my numbers are slightly lower than yours.
If you want to work in the Bay Area Hastings is better financially and regarding employment.
Did you apply to any lower ranked schools? You might be able to get a full-ride at USF. Taking out $100K+ with a small chance of biglaw will take a lot of time to repay.
Engineering is a solid background. It should significantly help with employment as long as you stay within something science/math related. Hastings promotes itself as "big" in IP.
