I would call them to see what’s up.
No news is no news and they haven’t provided you with any.
Job applications are a two-way street, meaning that you bring just as much to the table as they do. Sure, they hold all the cards with having the job but you also took your valuable time to interview with them.
Give them a call and see what’s up.
At the worst, you will annoy them and/or they will tell you that they gave the job to someone else.
At the best, you may get a job offer for still being interested or perhaps a second interview.
Far too many employers use stalling tactics like this rather than being assertive in telling someone that they didn’t get the job.
But then again, there may be circumstances that prevent them from making a decision until then.
