Went for an on-site interview in March. Informed by a talent acquisition team member (not from Singapore) to contact said person once I reached, but they were uncontactable. Told the security guard my situation and he just told me to wait and someone will come and bring me up. Had to wait at the lobby for an extra 20 minutes. Both interviewers were professional. At the end of the interview, was told I will know the outcome in 2 weeks but I never got a response even after emailing and sending follow-up WhatsApp messages after a month. For such a big company, it seems very unprofessional. It's not that difficult to send a rejection message or email, feels like I dodged a bullet.
