人與人互動時皆會產生第一印象，為了維持好的第一印象，印象管理就很重要。本研究以疫情時代的實體面試為情境，探討不同人格特質的求職者（外 向 vs. 內向）在應徵不同職位（會計 vs. 公關）時配戴不同樣式的口罩（淺藍 色 vs. 彩色花紋），會如何影響面試官對其所產生的印象，包括職位適配性、 可信度，與勝任力。經過線上實驗法，研究發現：外向應徵者在職位適配性、來源可信度、勝任力皆顯著大於內向者；應徵會計職位的適配性、來源可信度顯著大於公關；口罩樣式與三者皆無顯著差異，但內向者在面試會計職位時， 配戴淺藍色口罩的適配性顯著高於花紋口罩。

 To maintain a good first impression, impression management is vital. This study focuses on physical interviews under COVID-19 pandemic to explore how different styles of face masks （blue vs. multi-colored） worn by job applicants with different personality traits （extrovert vs. introvert） for different positions （accounting vs. public relations） affect the impressions of job match-up, trustworthiness, and competency of interviewees. The study found that extroverted candidates had significantly higher job match-up, source credibility, and competency than introverts; accounting candidates had significantly higher suitability and source credibility than public relations candidates, and face mask styles did not differ significantly from all three, but introverts’ job match-up with blue face masks were significantly higher than multi-colored face masks when interviewing for accounting positions.
