If a potential PhD student asked to pay you a visit before application, what do you expect from the student during the visit?

I was emailing a professor a while back if I could come visit her and her lab as I want to apply to her lab for PhD. She agreed. Now I'm scared and lost as I don't know what she expects from the visit. What should I do to impress her? Is it okay to be brutally honest*? Can you give me questions that a PI would ask? Any advice would be highly appreciated. Thanks!

*My research experience is kind of all over the place. They're all about one research topic but they're not like a flow that aims to achieve one thing. They're all good and valuable experiences but it's like they don't make up one story or they're different beginnings of different things. It's not my fault. I can't freely do what I want to do due to a lot of things, mostly funding and shitty equipments. And also my current PI keeps changing her mind.

That's fine; you're not a grad student already so you're not expected to be pulling together huge amounts of disparate work to form a big cohesive thesis.  A variety of skills is good; a potential supervisor will be looking more at whether you have some idea of what research is like (so you know what you're getting into), whether you're reliable/interested/take initiative, and whether you have good references.

Use this visit to try and demonstrate these things, and to find out whether you're a good fit for each other in terms of management style and research interests.
