There are several means by which you can find out about possible job opportunities. Some methods require more "leg work" than others do; some will require more advanced planning (e.g., contacting alumni/ae and parents). You should consider each of the following options:
Talk to as Many People as Possible
Many jobs are advertised through word-of-mouth. If you talk to past employers, friends, professors, family and alumni, let them know what it is that you are looking for; they will often give you a name and number of someone who may be able to help you. Talk with a Career Advisor about ways in which you can get in contact with alumni/ae.
Create Your Own Opportunity
Be creative! If there is an organization that you are interested in working for or a position you would like, take the initiative and get in touch with prospective employers. For Example: Career Search is a great way for you to locate information on many employers in a variety of career fields.
