Albert Einstein's genius extended in many directions, including how to write. Einstein gave this advice: "If you are out to describe the truth, leave elegance to to the tailor."
In my writing, I try to use language that is plain and direct. Too often, I read resumes that are cluttered with details that are not relevant to hiring managers. In many cases, clients use jargon that will only be understood by their current employer, the job they want to leave. How can you avoid this problem? Read what you write through the eyes of you intended audience. For resumes, that means recruiters and hiring managers. Use language that speaks to what they need and understand. Simple and clear wins the day.
