Relax. You're a new grad, of course you don't have work experience. If you did any projects, include those. Also, if you used any CAD programs or FEM's put those in.
Look at each job req you're applying for and see what they want. Include any particular course work that applies.
For an engineering job, you're really trying to get your rez past the IHR screen to the hiring manager. If they list a lot of buzzword, try to include them in you rez. If they say they want experience with the DOORS requirements management software and you've never heard of it, do a search, find the vendor (IBM) and learn a little about it. Then, state you are 'familiar' with it. That gets the buzz word past the auto screen.
You know if you do your rez in just about any word processor, you can simply add a string of buzzwords at the end, then delete them. Open the file in a txt viewer, you'll find they're still there, just not displayed. I'm not sure, but I'll bet that gets picked up by any auto screen program.
