The applicant's summary is created by an algorithm.
The algorithm scans a CV, breaking it down into sections of information. For example, we know: what is employment history; what is their most recent employment; what are their dates of employment; what is their most recent job; how long have they worked, what is their job title, what have they done, who is the employer? Etc, etc.
Based on this information the algorithm makes a best-guess at their level of work experience and summaries in a paragraph that we hope is useful when reviewing CVs. But it isn't perfect, so we apologise for any mistakes.
