Preemployment Boutique Firm

I've been trolling around these forums for a while but this is my first post.

So, after some laborious cold calling I managed to make some headway towards earning internship. Someone at a satellite office of a boutique firm forwarded my resume along to a higher up HR rep at the firm's headquarters. Lo and behold, I get an email the next day telling me that they have a paid position available. They told me that we'd move on to get some pre employment/hire paperwork done.

Does this mean that I'm very likely to get the position? I've tried to find a definite answer but nothing really came up.

I only ask so that I have some more perspective moving forward.

Thanks guys :)
