CompAsia Retail Operations interview questions

The whole interview/ hiring process is such a joke. The HR are the one that ask me if i am available for new job then i have pass their interview (the hiring manager is satisfied with my performance) and HR have also breif me through the whole salary package and incentive. Everything went out so smooth and get inform to wait for offer letter within 1 week......then thats the END OF THE STORY 🤣. The HR went MIA no reply whatsapp / phonecall just nothing at all like all of the interview process just happen in my dream. Moral of the story- DONT EVER RESIGN FROM CURRENT JOB BEFORE RECEIVING YOUR OFFER LETTER~
