Across WSO you can find some great advice on how to approach an upcoming interview, but there's a paucity of science on the matter. However, the April 2015 Journal of Business and Psychology offers a study that looks to the effects of anxiety and other factors that may affect the quality of one's interview. In particular, "Behavioral Expression of Job Interview Anxiety" aims to:
[I]nvestigate (a) the behavioral cues that are displayed by, and trait judgments formed about, anxious interviewees, and (b) why anxious interviewees receive lower interview performance ratings. The Behavioral Expression of Interview Anxiety Model was created as a conceptual framework to explore these relations.
ScienceDaily has written an article summarizing the study that delves further into the results obtained by the researchers. Not surprisingly, anxiety is a bad thing, but one of its manifestations is particularly interesting:
Feiler and Powell found that the speed at which someone talks is the only cue that both interviewers and interviewees rate as a sign of nervousness or not. The fewer words per minute people speak, the more nervous they are perceived to be. Also, anxious prospective job candidates are often rated as being less assertive and exuding less interpersonal warmth. This often leads to a rejection from interviewers.
The researchers go on to say that an interviewee should strive to be assertive and interpersonally warm, rather than focus on other displays of anxiety like nervous tics.
How would you monkeys suggest an interviewee go about being assertive and interpersonally warm? Have you ever dealt with a slow talker during an interview? Anyone come across someone who talks too fast?
