Zij Werving & Selectie

ZIJ maakt het verschil ('ZIJ makes the difference') is a Dutch recruitment firm established in 2007, specialising in office support placement across professional organisations in Amsterdam and the Netherlands. The firm recognises that strong organisational support professionals, secretaries, administrative assistants, office managers and financial support staff, form the operational backbone of high-functioning enterprises, particularly within sectors where precision, confidentiality and tempo demand excellence. ZIJ positions office support not as a peripheral function but as essential infrastructure determining organisational quality, continuity and cross-functional collaboration.

The firm specialises in placing talented support professionals across legal practices (advocatuur), consulting firms, accounting and tax advisory practices, business service providers, marketing and communications functions, interim and ZZP (freelance) professionals, and payroll management roles. ZIJ's unique approach extends beyond résumé matching, incorporating personality assessment and cultural fit analysis to ensure sustainable long-term placements. The company developed the Milly Pie planner, a tool reflecting its deep understanding of support professional workflows and organisational needs. ZIJ places professionals including notarial secretaries, legal assistants, office managers, human resources support staff, financial administrators and executive assistants into roles where they can meaningfully contribute to organisational success.

Operating from Amsterdam at Prinsengracht 151A, ZIJ emphasises transparent communication, careful candidate-role matching and genuine partnership with both candidates and employers. The firm believes that placement success hinges on understanding not merely candidate experience but their personality, energy and values alignment with the employing organisation. By building sustainable matches that benefit both support professionals and their employing organisations over years rather than months, ZIJ positions itself as the specialist in office support recruitment for professional services sectors where discretion, reliability and organisational knowledge become competitive advantages.
