There's a lot more to a successful job interview than looking right and having a nice resume. You must be prepared with a background on the company's history, mission and brand and information about the specific job position. You must be ready to answer a lot of challenging questions and prepare anecdotes if necessary. Arrive early to have time for a little deep breathing to decompress before the interview.
Look at the kinds of questions job interviewers tend to ask and compose answers to them. Some of the top questions include: Tell me about yourself; why did you leave your old job; why do you want this job; what are your strengths and weaknesses and tell me about a time when there was a conflict, problem, crisis, and how you handled it. Research the company and prepare a positive, pro-company answer about why the job appeals to you. Some possible job interview questions are listed on Monster.
Get some questions ready for the interviewers. Exclude those about compensation and benefits. Ask instead about what happened to the person who worked the job? What can they tell you about the corporate culture? What are important things they're looking for for this position? What are the best and worst things about this job and this company?
Plan your interview wardrobe at least a few days ahead of time in case there's a splotch on the shirt or moths attacked the suit. Make the outfit is neither too formal nor too casual for the job but is appropriate: a suit for an office job, for example and a pair of nice slacks and a shirt for a more casual work environment. Make sure there are no stains, rips, or worn places on the clothing.
Have a few copies of your resume, recommendations, a list of questions for the interviewer and possibly a copy of the job ad in your briefcase. Bring examples of your work if it's applicable. Print out directions to the building, instructions about where to park and information about the name of the person conducting the interview and how to find that person's office and bring those instructions along.
Whatever means you require to get to the interview, make sure you leave yourself plenty of time so you don't arrive flustered. If driving, leave at least 20 minutes earlier than the directions say you must in case you get lost. If taking public transportation, make sure you know which trains or buses you have to meet and how much the round trip will cost.
