A chronological interview is a style of interview in which you will be asked to talk about your life in rough chronological order, usually from your school days through to the present day. You may be asked to explain why you made certain choices, or why you think your background and experiences make you a suitable candidate for the job you have applied for.
The chronological interview is less structured than a standard interview as assessors are trying to see the reasoning behind each life decision. They may ask you to elaborate on certain points of interest.
Candidates undertaking this type of interview are often asked to complete a career history form in advance, or minimally provide a CV.
