I had an online interview—will I still receive an email if I’m not accepted? Does the fact that they didn’t check my ID mean I wasn’t accepted?

This is Hara, Chief at Universe Club’s Yokohama branch. If you passed the screening, the club would contact you to arrange a second interview, so unfortunately, it seems likely that you were not selected. That said, we can’t say for certain. If it’s really bothering you, why not check with the LINE account or email address you used when booking the interview? Best regards.
