Hey anonymous,
No, it's definitely not normal for any location to take so long to communicate the final results (it may take 1-2 days; in some exceptional situations a bit longer, but definitely not 2+ weeks). And, yes, regardless of the outcome, they will always communicate it!
Thus, I would recommend you to send them a very polite follow up email asking if they have a date on when they will communicate it to you (do not ask directly why didn't they say anything yet or if you have got an offer or not).
PS: despite not being a normal situation... this happened to me too. I just got an interview 2 or 3 weeks after the final interview, and at the time the interviewer told me that he had completely forgotten to call to tell me that I passed. 10 years latter this gives a funny story to tell :D
Best
Bruno
