Being long-winded during an interview makes you sound chatty and unprepared. Avoid this common blunder by keeping your answers to about 60 seconds or so during an interview (unless the answer really calls for alot more detail). You can perfect this by practicing answers to typical interviewing questions ahead of time. Not only will you sound intelligent and polished, but you'll also be less nervous knowing that you were prepared.
During a job interview, what you convey non-verbally may be just as important as what you communicate verbally. Interviewers typically take note of a candidate's non-verbal cues as they evaluate their skills and qualifications. Facial expressions, hand gestures, posture, and tone or inflection of voice all indicate a candidate's level of confidence and overall interest in the role. Prior to an interview, have someone you know ask you "mock interview" questions, then have them offer feedback on any non-verbal habits that may be distracting or unprofessional.
There are many reasons as to why you should never decline an interview with a potential employer or recruiter. Not only do you have the opportunity to practice your interviewing techniques, but you never know what kind of valuable contacts you may develop from the encounter. Maybe the current job opening isn't "the one for you", however, a few months from now, the ideal position could become available. Making favorable impressions and networking with various people is an important part moving your career in the direction you want.
When someone asks an open-ended question, such as, "Tell me a little bit about yourself," nothing can lose a listener’s interest faster than an over-detailed, rambling response. A well-prepared and practiced introduction is likely to capture an employer's attention and leave them wanting more. Use descriptive statements which relate to your skills and achievements. Whether in an interview or just networking, a good initial presentation will set the stage for a positive and pro-active conversation.
The key is to sell yourself by highlighting not only the knowledge, skills and abilities you could bring to the company, but also your accomplishments. As you answer all interview questions, make sure you are in a sales mode. Is the interviewer (the buyer) getting the information they need from you (the salesperson) to make an informed decision to buy from you (offer you the job). Don't forget to close the sale by asking for the job!
