Hi, I got an invitation from a graudate school, where I applied for a PhD program ,to attend a graduate students recruitment event. Does that mean I have been selected in the program? How likely will I be getting into the school? Any answers/ experiences is appreciated.

What do you think? Lets think about what you said?

Let me help, the invitation is for recruitment event, not admission.

In many cases grad school invites you only when you are a possible candidate. There is a high likelihood that you will be selected, yet it does not guarantee. Good Luck Bro !
