Abstract: When learning a second language, communicative competence as defined by Canale and Swain (1980, pp.27-35) is key. We don’t need to know all the words, but when we say them, we should be aware of our facial expressions, as they can improve communicative competence related to nonverbal communication in interviews and presentations. In this experiment, 12 students of varying but classifiable EFL experiences had their mock job interviews recorded and in both Japanese and English. These facial expressions were evaluated using a Kinect camera (with our modified algorithm) and a human judge. In an earlier study, only the Japanese facial expressions had been assessed (XXXX, 2019). Using an Action-Research methodology, we analyze differences between L1 and L2 replies to standard job interview questions and hone our methods. We hope our research helps students to become successful at job interviews in any language.
