With interviews being generally an unnatural environment applicants generally spend time preparing for the interview, looking into the company history, preparing answers for generic answers that are usually asked for job roles of that criteria. This would inevitably lead to the answers given being unrealistic responses of how an applicant may act in a role within an organisation. This simply highlights the importance of interview containing questions which are going to show a realistic response to show an applicant's approach and ethos towards their working life. During the interview this can be achieved by adding unstructured questions which will allow the interviewer to add and expand on answers given to try and get a more realistic and honest response which will further add to the value of the responses given from a candidate. This can also work well within a structured interview situation, as having an opening for several unprepared questions, can give a candidate further chance to show their true capabilities. Taking into account unavoidable effects (e.g. Anxiety, signs of being Nervous and body language) of environments like Interviews, consideration needs to be taken by the interviewer to account for these. Often anxiety levels can be raised for an applicant during interviews which can an effect on the responses and conduct during the interview which may result in the applicant not showing their full capabilities. A selection of Undergraduates took part in a mock interview model with peers, which shows sustained levels of raised anxiety before and during the interview, followed by a significant decrease directly after. (Therese Macan, 1999: 209). During an interview it has to be taken into consideration that responses given can sometime be not a true reflection of a candidates natural response in any other situation, so allowing time and a chance to develop an answer is crucial to maintaining a high level of validity from the responses given.
