It has been 2 weeks from the date of interview.
As the hiring manager said it would take 2 weeks so I have send an email to follow up on Monday.
But it has been 2 days and no reply from them.
Is it indicated I failed already?

Yeah, in the beginning, i tot it was failed.
Guess what, I got the job already.
Now it has been 2 months I have been working here.

I think I might have shoot myself in the foot during an interview. When asked about "why do you want to leave?" I answered something like to explore new opportunities and learn new things as what I currently do in my company is quite limited(in terms of being exposed to new technology). They ask did I do any self-learning to update myself.

To be honest, I didn't because my current job is quite hectic and a lot of support issues. I was a bit speechless. Do I have to put more self-initiative effort? My current work have sapped a lot of energy out of me. Sometimes even have to support on weekends. I just want a free time of my own too without thinking more on technologies and programmings and frameworks.. T_T
