At my most recent job I assembled many types of prefabricated buildings from garages to machine shops. I used impacts, concrete drills, jackhammers etc. and gained experience with many tools and learned a lot of tricks. We build everything from the ground up so I set the forms & poured concrete, frames, insulated, and set the tin. The job before that I did inventory to start but then got offered the job to locate/swamp for a boring crew and for the last month or so of the job I was setting anchors. I have a good amount of fast food experience and various skills from that, and other than that I've done short summer things like a pumpkin patch, roofing, painted barns etc. just to make money when i was in school.
I have the Work Keys readiness certification, Heres a link to the document
