Tell them you're graduating and want more time to decide on what to do with your career, that you're unsure of whether you'd be a better fit working more on the tech side of things. Say this to the hiring manager. This gives him/her two possible choices you'll like: (1) you get more time to decide, i.e., interview elsewhere or (2) they recommend you for another team and you get an accelerated interview there. Or (3) they stick to their offer at which point you can re-approach this decision after considering your backup plans. In the unlikely event this approach results in them rescinding the offer, either you lack tact or it's not a place you want to work at anyway.
