I do two or three resumes. One is to feed the machines, and it is in plain text format, with Arial. There is no special formatting, no bullets. It is in a completely chronological, even when it doesn’t make that much sense for a human to read it this way.
The next is for email, and that is also in Arial in Word and it also uses a fairly generic format. This is for headhunters or HR departments, who often want to edit out contact information.
The last is a PDF version that I can email or bring with me to an interview. I designed it in InDesign with appropriate spacing and leading. It is strictly for human eyes and nicely formatted, using an attractive font that is not Arial or Helvetica but not bizarre. It is in two columns on the page where I list my positions and accomplishments, with my education in an inset box.
