You have spent 20-30 minutes with this person, asking questions, getting advice and
sharing a little about yourself. Thus begins your contact network. The person has
taken time to share with you; in other words, he or she has invested time in you.
Most people like their investments to pay off. Most people will feel good about
your staying in contact with them. You do not have to call or write every week.
Just keep your interviewee posted on your research.
The interviewee may not have a job for you but may know of other employers or people
to which you may be referred. If possible, keep these people informed about your
progress. If you have done your job well, they will be interested in your final
choices. Ask for your contact’s business card and exchange one of your own, if you
have one.
