Do not get discouraged

Do not get discouraged
After several interviews without an offer, it is easy to get discouraged. However, it is important to remember that all you need is ONE job offer. After all, you have only one body, and therefore will only have time for one full-time job.
Having said that, it doesn't mean that you should sit back and continue doing what you have been doing. Perhaps you didn't get to the next round because you weren't prepared? Perhaps you didn't dress properly? Perhaps you were unable to answer some basic questions during the interview? Think about what happened during the interview, and make sure you rectify whatever that went wrong. Better yet, find someone who is already in the work force to give you a mock interview, and see what the feedback is.

Be prepared for behavorial questions

Be prepared for behavorial questions
Behavorial questions are the ones that are open-ended, the ones designed to find out about your experience. This type of questions, common during mid-level interviews, have been on the rise for on-campus interviews as well. An example of the behavorial questions is, "Tell me a time when you were under extreme pressure, and how you handled it?"
Preparation makes a big difference in how you'd perform in answering this type of questions. Also, before you walk into the interview, think about the different situations that you have gone through, whether it be pledging for a fraternity (I personally find this a great one), completing a project, your part-time job, or any other situation you can think of. This way, when the questions come up, you won't need to come up with the example right then and there.

Dress well

Dress well
Dress weel is to show professional courtesy. The interviewer is dedicating his or her time for this interview, and he/she would expect the candidate to give the interview at least an equal weight. A well-dressed candidate leaves an excellent impression and projects the image that he or she really cares about this interview.
This rule applies even if you are interviewing for a company known for its casual dress policies (such as many of the internet companies). Even in such cases, dressing up cannot go wrong. I have never heard any recruiter complaining that a candidate dresses too formally for an interview. However, many a candidate has been hurt by not properly dressed for the interview.
