Lisa Johnson Mandell was in her late 40s when she suddenly found herself without a job. Although she made sure to show off her 20-plus years of experience as an entertainment reporter on her résumé, after countless job applications went unanswered, her husband gave her the hard truth. "He said, 'Lisa, don't hate me, but you really look kind of old on paper,' " she recalls.So Mandell removed key age indicators from her resume, such as the year she graduated from college and the lengths of time that she was employed. "As soon as I sent out this new résumé that wouldn't tell anybody how old I was, I started getting responses—I'm not kidding you—within 20 minutes," she says. "And, in two weeks, I had three full-time job offers."The result wasn't just a new gig, either—she also wrote a book, " Career Comeback: Repackage Yourself to Get the Job You Want," in which she shares strategies for giving a resume a more youthful spin. "Somebody in their 20s looks at 20-plus years of experience and puts you in the same age group as a mother or grandmother," she says. Of course, in an ideal world, experience should trump age, but Mandell adds that "if you're really intent on getting a job, you have to make concessions."

If you’re a ball of nerves during a job interview, we have bad news: a potential employer can tell. Researchers at the University of Guelph in Canada studied job candidates to understand why some receive lower performance ratings. The findings, published in Springer’s Journal of Business and Psychology, revealed that talking speed was one of the biggest cues of interviewee anxiety, and often led to rejection.

After studying mock interviews with 125 undergraduate students, the researchers found that the slower people spoke, the more nervous interviewers perceived them to be. What’s more, both interviewers and interviewees recognized talking speed as a signal of nerves. The researchers suggested that candidates should concentrate on three key attributes during a meeting: warmth, friendliness, and assertiveness.

“Overall, the results indicated that interviewees should focus less on their nervous tics and more on the broader impressions that they convey,” study author Amanda Feiler said in a statement. “Anxious interviewees may want to focus on how assertive and interpersonally warm they appear to interviewers.”
