The key to successful recruitment is to ensure that the criteria of suitability are overt and relevant to the job itself. Once these criteria are agreed and shared it is possible to make more rational decisions about someone's suitability for a job, based on evidence rather than ‘gut feeling’ or instinct. Effective recruitment and selection should not be about the luck of the draw. Systematic planning and preparation will increase the likelihood of taking on the right person.

Incorrect assumptions about class, gender, ethnic group or physical ability, or any other type of discrimination, can cloud your objectivity in recruitment and selection. At worst this may contravene legislation that exists to protect individuals from discrimination.

The halo effect acts as a filter to any information that contradicts first impressions. For example, someone who attended the same college or university
