PhD Application process

A

Hi,

I was wondering if anyone can help me. I have recently applied for a fully funded 4-year Ph.D. I have received a very quick response and had my first interview (online, since the school is abroad). Apparently my interview went well, and I have been asked to prepare a presentation about one of my past projects. Of course, I have agreed to do it. Afterwards, I have been contacted by the university again and asked if I can do it in person (they cover all the travel costs), which I agreed to,again. Now I have found out that my presentation will be a part of the colloquium series for Ph.D. students and open for the school members.
I am really stressed and worried because my experience is more commercial than academic.

Is there anyone else who went through a similar application process? Any advice?

Thank you
