MCK Group interview questions

Had to fill up the usual forms upon arrival. After that a short chat with a HR staff. After which she told me that everything is fine and to expect a call within one week. She also mentioned that I could contact her if I had any concerns or questions. She told me to send her a photo of myself ASAP so she could proceed with the application. Didn't hear from her the moment I sent her my photo the same day. Can't help but wonder if it's because I'm wearing a tudung.
