An internal executive search is more efficient than an external search, which typically takes 120 days to find qualified candidates. Internal search specialists have deeper knowledge of a firm's needs and culture. Cost models for executive search include components like branding, sourcing, assessment, coaching, selection, and offers. Common models are salary-only, commission-only, or a hybrid salary-plus-commission model. Variations allow outsourcing basic searches or partnering with external firms on a lower commission. An example cost model was provided for recruiting C-level B2B sales executives internally.
