Also, if you can get some sample documents together it's very impressive. I've interviewed people for writing positions, and I was always surprised that people expected me to hire them without a writing sample. Something is better than nothing. If you finally land that interview, here are a few tips. First, always wear a suit.
Women can also wear a nice dress.
Guys, don't try this. You would be surprised how many people I've interviewed that showed up in casual dress. I'm not one for formal attire on the job, but you should always dress for an interview. Stress your writing skills. Tell them that you think it's an advantage that you DON'T have the ability to program.
