there was a test?

I've been interviewed by AmBank's subsidiary last month and took 3 tests which I believe I didn't do very well. Luckily I've been called by AmBank Group's hr personnel within 2/3 weeks after the first session and called for the 2nd interview with the hr. Asked the hr how many people were selected for the 2nd session, the hr said that I am the only one and it supposed to be the final interview (which I don't really understand what final interview means - some ppl said it is for the hr to concur). Thus, I went to the 2nd interview, further discussed on hr matters and the main concern of hr I believe was about the salary. It went well and I asked the hr bout my current status directly - "What is my status now? Am I accepted? Or..?" and the hr personnel said "Basically yes, you are accepted by the hiring department and recommened by the hiring department as well, and we are to get the final hr approval as to confirm the hiring". And she said it will take another 2/3 weeks to revert back as to prepare everything and get the 'signatures'. What do you think? Am I getting the job? Or still 50-50? 

It took me 2-3 weeks to wait before they finish the confirmation letter, but I decline the offer.
