I've always wondered this and wanted to understand the process as a freshman so I don't potentially burn any bridges or come off as creepy.
I understand that the best way to network is to connect with them on topics other than work, so in preparation, how far would you look as to what the person's interests/hobbies are? Would it come off as creepy if you mentioned you saw where they worked/graduated on linkedin? What about as far as what genres of music they like that you may have found on their facebook?
The situation would be different depending on the environment you're in, so let's say that an alumni agreed to grab coffee with you. Would it be creepy to say at the meet(given that its your first time meeting in person), "hey I noticed you like X artist. I actually went to one of their concerts a while back."
Thanks in advance for the replies, a couple networking events coming up this fall/winter and I want to make a good first impression.
