Omg I’m so glad I found this forum cos I am in the exact same predicament as you. I went for my unit preview early last week (most probably a different position tho, mine is a corporate role) but have yet to hear from them. They have been very responsive throughout the application process so this wait is making me very anxious. I am fine if they reject me (I fortunately have another offer already) but I just hope to hear from them ASAP as the uncertainty is giving me the nerves and anxiety lol... pls do share here if you do hear from them so that I have a rough idea whether to just give up waiting for mine... all the best!
