Working as part of an in-house recruitment team, you receive a lot of approaches from contingent recruitment agencies all offering the same ‘solution’.
The main selling points in an initial approach from said agency are exactly the same. They are industry experts, work with my competitors and can provide a recruitment solution which is better than agencies we currently work with. When challenged over this, they go on to profess that they are different from other agencies without any real ability to provide a differentiator.
