Work samples and tests are a great way to assess a candidate's work ethic for team culture. They can measure how well they perform relevant tasks, solve problems, and apply their knowledge and skills, as well as demonstrate how they cope with pressure, ambiguity, and complexity. For instance, you could ask them to present their analysis, recommendations, or solutions in writing or verbally for a case study or scenario that simulates a real-world challenge or project. Alternatively, you could administer and score a skills test or assessment to evaluate their proficiency in a specific area such as coding, writing, or design. Additionally, you could review their portfolio of previous work which can showcase their achievements, creativity, and quality. Asking them to explain their process, challenges, and results is also beneficial.
