If you're sending out resumes without knowing what your ideal job is, you're wasting your valuable time.  So, before shipping off another application, be sure to sit down and define what type of job you're looking for. Try to make an interview bucket list. This way,

you'll have have a more focused search and can create a customized resume to match.

Do you have bad interviewing habits? In other words, do you assume you're on a first-name basis with interviewers? Or do you slouch in your seat?  If so, be sure to learn about appropriate body language and ways to address interviews so 

that you can always come across as a confident candidate with plenty to offer.

Many interviewees get stuck with the question, "Why did you leave your previous employer?"  While you may want to say that your previous boss was a jerk, this is not the time or place to mention it. So, if you're asked this question, just say you are looking for 

new opportunities that align with your career goals.

While job fairs may feel like impersonal functions for individuals who are desperate for work, nothing could be further from the truth.  In fact, some great networking opportunities can be found at job fairs, not just with company representatives but with other job fair attendees.

When interviewing, company representatives are watching your every move, including how you're dressed.  If your attire is too casual, sexy, or plain outrageous, your amazing resume or interviewing skills may do little to get you hired.

Another mistake to avoid is not following up with an employer after your interview.  To make sure you remain on the employer's mind, send a follow-up email of about three or four paragraphs that summarizes your skills, reiterates your 

eagerness to be hired, and thanks the entire staff for their time.
