Research About The Company
An interviewer may ask how you perceive his company’s position in its industry, who the firm’s competitors are, what its competitive advantages are, and how it should best go forward. For this reason, avoid trying to thoroughly research a dozen different industries. Focus your job search on just a few industries instead.

Clarify your “selling points” and the reasons you want the job
Prepare to go into every interview with three to five key selling points in mind, such as what makes you the best candidate for the position. Have an example of each selling point prepared (“I have good communication skills. For example, I persuaded an entire group to …”). And be prepared to tell the interviewer why you want that job – including what interests you about it, what rewards it offers that you find valuable, and what abilities it requires that you possess. If an interviewer doesn’t think you’re really, really interested in the job, he or she won’t give you an offer – no matter how good you are!

Anticipate the interviewer’s concerns and reservations
There are always more candidates for positions than there are openings. So interviewers look for ways to screen people out. Put yourself in their shoes and ask yourself why they might not want to hire you (“I don’t have this,” “I’m not that,” etc.). Then prepare your defense: “I know you may be thinking that I might not be the best fit for this position because [their reservation]. But you should know that [reason the interviewer shouldn’t be overly concerned].”

Prepare for common interview questions
Every “how to interview” book has a list of a hundred or more “common interview questions.” (You might wonder just how long those interviews are if there are that many common questions!) So how do you prepare? Pick any list and think about which questions you’re most likely to encounter, given your age and status (about to graduate, looking for a summer internship). Then prepare your answers so you won’t have to fumble for them during the actual interview.

Line up your questions for the interviewer
Come to the interview with some intelligent questions for the interviewer that demonstrate your knowledge of the company as well as your serious intent. Interviewers always ask if you have any questions, and no matter what, you should have one or two ready. If you say, “No, not really,” he or she may conclude that you’re not all that interested in the job or the company. A good all-purpose question is, “If you could design the ideal candidate for this position from the ground up, what would he or she be like?”

If you’re having a series of interviews with the same company, you can use some of your prepared questions with each person you meet (for example, “What do you think is the best thing about working here?” and “What kind of person would you most like to see fill this position?”) Then, try to think of one or two others during each interview itself.
