Wondering if I have a job locked down

I am graduating in a couple of weeks and I recently caught wind of two different management jobs for the company I am currently interning with. Right after my current boss submitted my resume for consideration I had a presentation with senior management, and the two hiring managers. They left the presentation blown away with what I had to say. Next thing I know they are inviting me to the headquarters for an interview, but when I got there they mainly just talked me through the roles and asked which position I am more interested in. I would be working in a position where I am mainly trying reach out to individuals around my age. I also have various referrals from my own boss and a few of his superiors. And finally the AVP of the division reached out to me after my meeting at headquarters, saying he saw me there and was wondering how everything went and saying he would put in a good word for me (He has only met me once and he already knew I was there to talk about a position without me saying anything).

I also know they hired an outside research firm and they ended up covering everything I covered in my own presentation.

I know I shouldnt be counting my chickens before they hatch but considering how I have been treated up to this point should I be worried about getting rejected? I've kept in contact with the boss of both the hiring managers throughout the process, but the hiring managers themselves have kind of just stonewalled my emails.

Thanks for the advice!
