Job interviews never seem easy. To get a job, you may have more interviews than you can count. To succeed in an interview, you should pay attention to the following common mistakes.
Lack of proper preparation. Failure to gather information on the company and the job before the interview makes a very poor impression on interviewers; it suggests that you really are not that interested in the position.
Inappropriate personal appearance. Consider the nature of the position and dress accordingly. When in doubt, dress somewhat more formally than you think would be expected for the job. Be conservative (保守的)and pay attention to details, such as shiny shoes, neat hair, etc. First impressions are very important.
Poor non­verbal communication. In addition to what you are saying, your non­verbal behavior is very important in an interview. Are you making eye contact? Are you listening attentively when the interviewer is speaking? Are you giving a firm handshake when greeted by the interviewer(s)? Are you nervous during the interview? Practice with a friend or in front of a mirror to assess these factors.
Poor attitude. Self­centered behavior (i.e. a “what's in it for me” attitude) is very poorly received by interviewers. Ask yourself what you can contribute to the company? What skills and experience would you bring to the job?
Failure to ask questions. Employers will assess your interest in the company and the position by the types of questions you ask. Proper research prior to the interview will help ensure that the questions you ask are intelligent ones.
Being disorganized. Make sure you arrive at the interview a few minutes early so that you have time to get calm and check your appearance. Arriving late is simply unacceptable, so plan for the unexpected. Always bring an extra copy of your resume (简历) and references to an interview.
Over or under­answering questions. For most interview questions a “Yes” or “No” answer is not appropriate. Provide more details for an employer and cite (引用) examples from personal experience wherever possible. Do not, however, talk endlessly and feel that you have to keep speaking if there's a silence. When you have said what you want to say, stop talking. If you do not understand a question, seek clear explanation before responding.
Failure to send a thank­you note or card following the interview. Take the time to send a thank­you card,which can make an important impact on an employer. Not only does it show your sincere interest in the position, but it also helps make you different from other interview candidates.
