Attending an interview with the intent to impress the hiring manager is dangerous if you go about it in the wrong way. Below are some things you can do to maximize your chances of getting the job.
{#blank#}1{#/blank#}
True, sometimes interviewers aren't prepared themselves, but that doesn't mean they'll forgive you for the same mistake. Developing and following a plan at the beginning of a job search has a significant impact on its success. Research the job thoroughly. Think about how your previous experience qualifies you and how it compares to the work on offer. Set "process goals" to keep you on track toward your larger career goals. "Process goals" aren't big-picture objectives. They're "roll up your sleeves and make it happen" objectives.
{#blank#}2{#/blank#}
You can't think of any personal weaknesses, you’ve overcome all your weaknesses, or you say you haven't given it a lot of thought. Mistakes? Not you. No one progresses in a career without making mistakes and learning from them. Trained interviewers will be looking to see if you readily acknowledge and admit your weaknesses and can describe mistakes you’ve made and what you learned from them. Never give a measured response that sugarcoats reality to a tough interview question about your past.

If you were a 6-foot, 5-inch, 250-pound Frenchman with strong arms and a bushy beard, would you apply for the part of Little Orphan Annie on Broadway? How ridiculous that image is. If you don't have an accurate understanding of what the job is all about, your opinion of how well-matched you are will be based on an inaccurate foundation. For example, sales professionals are expected to possess excellent communication skills, time management and organization skills. Make sure you have a full job description from the employer so you can match your skills to the job's requirements.
{#blank#}4{#/blank#}
The best way to ensure a good first impression is to dress smart. What is appropriate depends on the particular employer and job but, generally speaking, it is better to dress formally while remaining comfortable. If you are unsure what to wear, you should always go with the most conservative, professional option. What you are wearing tells employers a lot about how serious you are about getting the job. The more confident and polished you appear, the more likely you are to leave the interviewer with a positive impression of you.
{#blank#}5{#/blank#}
Learn as much as you can about how the interview will be conducted. Employers are looking for the candidate with the best knowledge and experience, but rarely do they hire for work skills at the expense of social skills. If you lack self-awareness, it shows. And it doesn't look good. Be on time for your interview. Be aware of your body language. Even in the critical small talk before the interview, make eye contact with your interviewer to convey confidence when you're speaking, smile when it's appropriate, and look alert.
