  Schedule plentiful interviews. Use every possible method to get interviews—answering advertisements,using search firms, contacting companies directly, surfing the Web, and networking. ____72____

  Follow up.____73____ Then, some weeks later, send another brief letter to explain that you still have not found the perfect position and that you will be available to interview again if the original position you applied for—or any other position—is open. Do this with every position you interview for, and you may just catch a break.

Make it your full-time job. You can’t find a job by looking sporadically(偶发地). ____74____ If you’re unemployed and looking, devote as much time as you would to a full-time job. If you have a job while you’re looking, figure out an organized schedule to maximize your searching time.

Network vertically. In the research stage of your job hunt, talk to people who are on a level above you in your desired industry. They’ll have some insights that people at your own level won’t have, and they will be in a good position to hire you or recommend you to be hired.
