To follow up on what gravenewworld just wrote,
Let's list the TOP THREE WORST WAYS TO FIND A JOB:
Number Three: Going to job fairs
Congrats, the only people who are there are HR reps (your worst enemy in the job hunt) from companies that weren't able to find employees other ways. Look closer and you'll see a third of the jobs are government and a third are sales. At least you get some face time. . . along with two hundred other people.
Number Two: Sending out resumes
Once again, you'll be stymied by that evil of evils, the HR department. Guess what, all that time you spent writing the perfect cover letter and formatting your resume goes straight into the trash - as will your cover letter and resume after essential information is scanned or typed into the computer system. No one who matters will ever see what you wrote, and you are now data in a system. Best of luck!
Number One: Sending out resumes. . . on the internet
Wow, everything that sucks about sending out paper resumes, except now you're buried even farther in the (mis)information highway, the companies are even less interested in what you wrote, and you've made yourself a target for scammers to boot. Enjoy!
If these were the methods you used to look for a job and you failed, don't feel bad. Lots of other people make the same tremendous mistake. Now you get to go check out no less than three different books from your library on how to actually get a job, read them, and try try again.
