Like list recruitment, this requires specialist recruiters that have a personality that is suitable for approaching businesses and often, quite senior and successful candidates.

There are usually a number of hurdles for the recruiter to negotiate. Not least, the more senior a potential respondent is, the more ‘gatekeepers’ there will be before we are able to actually engage with the actual respondent.

This will often involve much telephone and email contact to ‘build a relationship’ before the actual recruitment can be carried out.

Due to a combination of this and the respondents’ diaries usually being booked up well in advance, this type of recruitment would usually require a longer lead time for the fieldwork.
