Many follow-up interviews by a corporate office are conducted by phone. If you are unable to express yourself appropriately, you may be passed over. It is acceptable to mention an experience even if it didn't turn out well. You may use this experience as an example to explain how you might do things differently.
Employers appreciate when students take ownership for their successes and failures.
During the interview, employers like to hear about real life examples rather than generalizations. Most employers feel that your past behavior is a predictor of how you will do in the future, so it is important to show how you have dealt with situations in the past. Ask substantive rather than general questions of the employer. Take the initiative during the interview and volunteer information. Some recruiters felt the interviews were one-sided and that they needed to draw out information about the student's experiences.
