After the candidates are chosen the hiring departments or personnel call them for interviews. When contacted the applicant will be told a time and what to expect.
Every company is different so prepare for any types of questions.
The interview part of the process helps the department decide on which candidates they favor. Interviewing gives them a chance to meet with the student face to face and determine many things about his or her personality, quick thinking, and whether he or she will be able to fit the needs of the position. If it is by phone he or she should note time differences and when the exact time of the interview is. Telephone etiquette should be practiced. As with any interview the applicant should be polite and friendly.
