At the undergraduate level, for Bachelors and other programs, interviews are very rare and only in cases where universities need further information to determine aid or other benefits to the applicants. And if the option is chosen, universities would then fix up and conduct a telephonic interview. This is more often an exception than a norm.
For the admission in business schools, interview plays an important role, as many B schools will conduct interviews in person, through their Alumni within the country of applicant or by the school’s representatives if they are visiting the applicant’s country for business promotion or for attending in college fairs etc.
Usually interviews are scheduled to take twenty to thirty minutes, but they may extend to fourty minutes or even an hour. The interviewer, who is typically the professor of your chosen department, will welcome you and check your name.
The professor questions first, letting you ask questions at the end of the conversation. It would be a good idea to prepare in advance one or two questions that indeed interest you about the program or institution. However, any questions should be well-grounded in information from the materials issued by the university.

Choose three areas most attractive to you among the courses. Preferably, choose areas from the core or major areas of concentration.

The questions you may be asked are as follows:-

What do you expect to gain from these studies?

What specific interest do you have within your field of study?

Why have you decided to apply to this university?

Where do you see yourself in the next five (or ten) years?

It is golden opportunity to put his best foot forward and in the door for the student. He can avail of this chance to press home his advantages, clear the doubts, answer queries and leave a favorable impression in person. Sometimes, even the most powerful documentation and strong admission packaging is rendered useless when the committee meets with the candidate and finds him lacking. This could be for reasons as inane and simple as his ignorance of simple knowledge such as do and don’ts of interviews, deportment issues or monosyllabic answers.

Guidance is provided from everything from what to expect to how to dress, to how to enter, telephone etiquette (if the interview is to be telephonic) to making a graceful exit. We work towards reducing the candidate’s anxiety, his fears and provides much needed encouragement.
