Wait after the interview...

I am currently waiting with almost two weeks since my first interview. I am in no rush as I have a job I love and I am only looking forward to a switch in specialty and advancing my career but this wait is starting to get agonizing. I contacted HR and was told I will know in a few days but I feel like with it taking this long that my chances are pretty low...

How long have you waited after an interview to receive an offer?
Yes, for my last job, 3 weeks from initial interview to official offer.
Well that gives me hope... Still waiting.
