The correct answer is: Questions tend to be more varied and more random

Rationale: This is a disadvantage because there may not be a clear interview strategy, and candidates may have trouble switching from one topic to another.

'A number of people see the candidate at one sitting' is an advantage, because it reduces individual bias, and saves time in sharing assessments (eg compared to a series of one-to-one interviews).

'Specialists can ask a questions about technical areas of the work' is an advantage, because a single interviewer may not be able to spot candidate weaknesses in technical areas.

'There is less opportunity for personal rapport with the candidate' is an advantage, because personal rapport may lead to favourable bias on the part of an interviewer.
