If you ever want to apply for a job that you don't qualify for; act really enthusiastic. Mention it's your dream job exct.

Next, research the contents of the resume. Do a bit of questioning. Specifically if you can look for reviews of products and look up complaints. Like IE "The HP4015 printers are so easy to take apart, they always tend to jam where it pulls up the paper, but if the rollers are replaced they last damn near forever..." They will think you know a lot more about the product.

Try to arrive early and be ready to make small talk. Especially for web cam videos.

With a bit of luck, you can get a job that you probably shouldn't be doing. Take lots of notes and ask questions when training and if you look the part you will be fine.

Other tips:

If you don't want to write a cover letter, put your resume in a sock. This way when they interview you; all they get is a sock.
