<human>: Can you succinctly summarize the text in 1-3 sentences?

Hello /r/Advice. I would like to apologise in advance for my poor formulation.

Im in the process of getting an internship. I had an interview online yesterday with a major corporation about getting my internship there at a really exciting project which is everything I've ever dreamed about.

The interview seemed to go really well. They seemed very impressed at my portfolio and the stuff I sent to them to show off my skills. Plus a HR person I've been in contact with called me and told me everything went amazing and that they were extremly impressed at my work.

But here's where it gets dicy, she started by asking me if I have had contact with any other company to which I replied yes (since I do, but I dont want to be at any other company) and then she asked me if it was okay if I got their response on Wednesday. I said yes.

Then she ended the conversation by giving me her number and telling me that I could contact them if I needed a reply sooner. This really confused me.

Have they already made up their mind? Will it increase my chances if I call them and tell them I need their answer sooner?

Im on the event horizon to going insane about this. Please somebody just tell me how I should react. Should I call, not call? What did she really mean by asking me? 

Help :(
<bot>: HR told me my interview at their company went great but then she told me that I could call if I needed their response sooner. Now what?
