With 15.1 million people unemployed in the U.S. and only 2.4 million available jobs, that translates into an average of 6.3 unemployed people for every job opening, according to the U.S. Bureau of Labor Statistics.

Despite these numbers, people found jobs when they treated their searches as full-time projects that must succeed, and persevering no matter how difficult it was. People needed to continually be on guard not to defeat themselves through their attitudes, actions, or omissions, said Tim Schoonover, chairman of OI Partners.

Following are the top reasons why people today are not landing the jobs they seek, according to career consultants from OI Partners:

• "Not over it yet" or expressing anger or disappointment with previous employer. During interviews, some people were acting wounded, angry, sad, or were becoming teary-eyed about being laid off. This couls make you appear unstable and communicate you didn't understand the business reasons for layoffs, said Schoonover.

• Failing to ask for the job, or not inquiring into what the next step is. You have a much better chance of getting a job if you ask for it. Close the interview by summing up what you could bring to the job and ask for the opportunity to deliver these results for them. Also damaging was not inquiring at the end of an interview what the next step was, and assuming you know it, said Schoonover.

• Not being able to personally connect with the interviewer. Chemistry is at the root of nearly every hire. Employers choose people who seem most likely to get along with others, and are the types co-workers want to be around.

• Lacking humor, warmth, or personality during interviewing process. Many job applicants were one-dimensional during interviews and were too focused on getting their talking points across. Don't forget to show qualities that could be a plus in the decision-making process, including humor in good taste, warmth, and understanding, said Schoonover.

• Appearing over-qualified for the job. Because of the lack of job openings, many people are applying for positions below their past income and experience. Address interviewers' concerns you might leave once the job market improved by countering that your experience would solve problems and create solutions with the ultimate goal of helping the company increase revenue. As a result, everyone's salaries would improve - including yours, said Schoonover.

• Failing to set yourself apart from others. Job-seekers must make the strongest case possible why they are the right person to hire. Specifically address what impact you could have on sales, profits, costs, productivity, complaints, or other areas within the next three to six months. Use quantifiable achievements from past positions to back up your performance promise, said Schoonover.

• Not showing enough interest and excitement. Companies are looking for people who are enthusiastic about working with them, and can motivate and inspire co-workers and direct reports. Communicate this in a variety of ways and express your enthusiasm for hitting the ground running.

• Not researching a potential employer and discovering latest news about them. It's critical to do your homework before an interview so you can prepare in advance the right questions about their current and future products and services to discuss during the interview.

• Focusing too much on what you want and too little on what the interviewer is saying. Listen carefully and analyze what an interviewer is saying, translating this into what you can do to help them fulfill their needs. When answering questions, be sure to match the communication and personality style of your interviewers, said Schoonover.

• Not following up frequently or aggressively enough. Many employers seem to be waiting for the absolute, ideal person to walk through the door. The decision-making process was much longer today. Your follow-up efforts need to be more aggressive and frequent than usual, without becoming irritating, said Schoonover.

• Trying to be "all things to all people." Devote most of your effort to what you know, what you do well, and don't try to stretch your actual qualifications too far. Mainly target jobs for which you have at least 75% of the stated qualifications.

• Not successfully transferring past experience to the opportunity. There are more opportunities in some job functions and industries than others. Be prepared to translate your past experience to fit the opportunity using quantifiable achievements, results, and terms that are relevant to the new position.

• Making an inappropriate personal presentation. Not wearing the right level of attire to an interview or sloppy personal hygiene. You only get one chance to make a good first impression.

• Over-explaining why your past job was eliminated or referring too much to your previous company. Don't spend a lot of time talking about your most recent employer, especially the reasons for leaving. If you have been laid off from a large company, communicate that you would fit in at a smaller employer, said Schoonover.

• Feeling you can "wing" the interview without preparation. Many job-seekers are not prepared to answer difficult questions. Prepare and practice a 90-second ver
