Shopee Copywriter interview questions

Was asked by an HR staff member to answer a marketing exam. Basically, situational essays (crisis management) and writing captions. After that, I was scheduled for an interview the next day at 2 PM. The day of the interview came and waited for the 2 PM call. However, it did not come. I have already thought of it as a RED FLAG. It was very unprofessional of them. So, I went on with my life. After 47 minutes, the phone rang. I gave it a try but I didn’t seriously answer the questions. It’s not worth it anyway. Overall, the interviewing experience with them was OK. However, they were unprofessional.
