No response after follow up email job interview. Did I not pass the interview?

I had a job interview a bit less than 2 weeks ago, and at the end of the interview one of the member arranged the meeting claimed “we are a fast decision maker, so we will get back to you in couple of business days”. After a week I sent them a follow up email, however they did not reply to me the remaining week. Is it safe to assume that I didnt pass the interview and just move on? Im actually having a last hope that they are still deciding, but this wont be the case right?
