Not every scholarship program requires an interview. Those that do can present a special challenge for which you may wish to prepare. The format and length of the personal interview vary widely from program to program. Some selection panels are very large, with as many as 20 people, others may have only one or two.
Panels can include people of any nationality, in any combination.
They may be all male, all female, or mixed. Some programs provide guidelines and fair, reasonable sample questions for their selectors, but there is no guarantee that all selectors will utilize the guidelines. Most selectors strive to be as professional as possible, but they cannot help but bring their own expectations and biases to the process. Even the most professional selection body is, on some level, subjective. An interview is an inherently dynamic situation, dependent on the interplay of personalities in the room.
