Preparing and rehearsing to answer interview questions is one of the most important things job seekers can do if they want to get hired.Great, confident answers can overcome showing up late for the interview, lack of a quality wardrobe and spilling coffee on the interviewer, but a lack of preparation can kill your job prospects, regardless of whether you scored perfect 10's on every other aspect. If you can't be bothered to spend 10-30 minutes of prep time in order to get the job, how is an employer able to expect that you will work hard on the job every day?Master these common interview questions and win your dream job.What Are Your Weaknesses?Don't say that you don't have any. Find a way to spin this in your favor.

Some interviewers will tell you never to actually talk about yourself personally. On the other hand, savvy hiring managers know that the most cost effective hires are those with personal lives outside of the office too. Staying fit, barbecuing with family and potential clients and attending industry seminars are all powerful pluses. Just don't tell them about your gun collection, secret society memberships and habit of drinking twenty shots of spirits back-to-back on the weekends.Past Employment DatesHave a copy of your resume handy for you to refer to.Where Do You Envision Yourself in Five Years?Don't go overboard and scare them into believing you won't stick around, or be too modest and make them think you don't have any ambition or drive at all. Ideally, you probably want to take your immediate supervisor's position so that they can move up and get paid more.
