I sometimes get contacted by recruiters on sites such as LinkedIn, asking if I am interested in a job they have available, and they usually want to make a formal connection on the network to share more details about it.
I feel unsure about how to handle this: All of the people in my LinkedIn network are people I actually know and work with now or have worked with in the past, and I am not certain it's a good idea to add people to my network based on communication that is based on a single message. On the other hand, I also wonder if I am losing out on potential opportunities because of this.
I would like more information from the recruiter, but don't want to formally add them to my network unless I have a real personal connection with them. What is the proper etiquette for handling this situation?
