Assessment Center
An assessment center is a structured multi-method evaluation combining written tests, role-plays, group discussions and simulations to assess a candidate's technical skills, leadership potential and cultural fit. Swiss employers use them for middle and senior roles where the cost (typically CHF 800–2500 per candidate) justifies the depth of insight.
Assessment centers have become standard for senior hires and specialist roles at Swiss SMEs. Rather than relying on interviews alone, you observe candidates performing realistic job tasks over half or full day, with trained evaluators scoring behaviour against role-specific competencies.
The format cuts through rehearsed interview answers. You see how a candidate handles pressure, collaborates under time limits and thinks on their feet—critical signals for leadership roles or technical positions where mistakes cost money.
When Assessment Centers Make Sense
Use an assessment center for roles where stakes are high: department heads, key technical specialists, or roles requiring cross-functional collaboration. For junior positions or high-volume hiring, the cost and time (8–10 hours per assessor per candidate) rarely justify the return.
Canton regulations do not govern the format itself, but labour law (ArG) applies: assessment activities must not discriminate based on age, gender, origin or disability, and must respect personal dignity. Data protection under revDSG also applies to test scores and observer notes.
- Typical exercises: case analysis, presentation, group problem-solving, one-on-one interview
- Cost ranges CHF 800–2500 per candidate depending on external facilitators or in-house delivery
- Duration: usually half-day (4 hours) to full-day (8 hours) depending on role seniority
- Best for roles with 100% Pensum, leadership responsibility or technical gatekeeping
- Plan 6–8 weeks lead time if outsourcing to specialist firms (many based in Zurich, Bern, Basel)
- Assessor training essential: untrained evaluators introduce bias and invalidate results
Your Legal and Ethical Obligations
You must treat all candidates identically in task design, timing and scoring criteria. If you run different exercises for different candidates, document why—role-specific modifications are acceptable, discriminatory shortcuts are not. ArG forbids discrimination; revDSG requires you store assessment data securely and discard it after a reasonable period (18–24 months).
Transparency matters. Candidates deserve to know in advance that an assessment center is coming and what it will cover. Hidden agendas or surprise elements damage your employer brand and may invite legal challenge if a candidate claims unfair process.
- Scorecards must define competencies in writing before the day begins—no retroactive moving of goalposts
- Keep assessor teams consistent; rotating observers introduces uncontrolled variables
- Disclose results to candidates within 2 weeks; be prepared to discuss scoring rationale
- Ensure assessors sign confidentiality agreements protecting candidate information
- If using external providers, confirm they carry liability insurance and understand Swiss labour law
- Retain records for minimum 2 years in case of later disputes
The Most Common Mistake
Running an assessment center without defined competencies upfront. Too many Swiss employers design exercises on the fly, then argue about what performance 'meant' after watching candidates. This invites bias, inconsistency and legal exposure.
The fix: 6–8 weeks before the assessment day, write a job profile listing 5–7 critical competencies (e.g. 'leads cross-functional teams under deadline pressure'). Design each exercise to measure specific competencies. Train assessors to score on rubrics, not gut feel. This rigor protects you legally and produces better hires.
- Competency drift: changing what you're assessing mid-process invalidates comparisons between candidates
- Assessor bias: one strong personality can dominate scoring; use blind review or multiple raters
- Over-reliance on group exercises: introverts may appear less engaged; balance group and individual tasks
- No documentation: if a rejected candidate claims unfair process, can you show your scoring logic?
- Skipping debrief: candidates who invest 8 hours deserve feedback; silence breeds resentment
- Wrong venue: a noisy, cramped office undermines the professionalism of the process
Frequently asked questions
- Do I need external facilitators or can we run an assessment center in-house?
- In-house is possible for straightforward exercises (case analysis, presentation) if you train assessors thoroughly. External specialists (typically CHF 5000–15000 per day) add credibility and objectivity, especially for leadership roles. For a first assessment center, external guidance on design is worth the cost.
- How do I avoid discriminating in an assessment center?
- Use identical exercises, time limits and scoring rubrics for all candidates in a cohort. Accommodate disabilities (extra time, quiet space, technology aids) as required by ArG without changing the task itself. Never adjust standards for specific candidates. Document all accommodations.
- Can I use assessment center scores to rank candidates?
- Yes, if your rubrics are clear and applied consistently. Scores are one signal; combine with interviews, references and technical tests. Never rank solely on assessment results. Be transparent: if your decision deviates from assessment scores, be ready to explain why to rejected candidates or potential challengers.
