Can a computer programme choose the right applicant for a job? Online assessments, scanning programmes, computer algorithms and the number crunching of social network data are all now part of the tool kit of the recruitment industry.

Traditionally a subjective process, Peter looks at this huge change in the way people are selected for jobs and asks whether technology can achieve the recruiters' aim of eliminating bias from hiring.
