NO.

This is very very bad form. People WILL remember you for this, and not in a good way.

A few things to consider... At this stage of your career it's not critically important that you work for any specific company. Having a job and getting some general experience in a level 0 position is going to be pretty much the same any place you go (unless you are maybe comparing a position at Facebook to a position at Coders, Inc., but it doesn't sound like that is the case).

You will more than likely get some experience, figure out what you want to concentrate on in your career, and then go that route in a year or three.

Pick a job offer. Turn down the other one gracefully. Tell the hiring manager of the job you decline that you'd like to keep in touch with them (and do so).
