Networking as part of the job search process has evolved past the stereotype of stiff people in suits, exchanging their numbers as they ask, "So what do you do?". Today networking looks totally different. It is a connection formed organically through mutual interests that provides value to both people. Networking as part of the job search process can look like many different things, including:
ALL THE TIME!!!
Networking is not some formal process that should only happen during certain times. It is an organic process of making connections to people with similar interests. If you spark up a conversation with someone in the grocery store, and it comes up that you are both interested in the same thing, take a moment to exchange contact information to keep in touch. Exchanging email addresses or LinkedIn profile information is a low pressure way to create a path for future contact.
Don't forget that networking involves an exchange that flows in both directions. When you reach out for the first time, share some information or tidbit that is valuable to the person you are communicating with. You want to make sure you are providing value to them, not just hoping they can help you. Be yourself, and let the conversation flow naturally. Real authentic connections grow over time and they must be nurtured. Keep in mind, most people love to share what they know, so asking questions is a good way to also start things off!
