Hiral - Youโll eventually have to evaluate them on some sort of a key skill needed for the role. Essentially, if not on what-they-have-done-in-the-past, it needs to be on what-they-learn-and-deliver that can be assessed.
For eg., If you are hiring for mid-seniority Content Marketing role, you may want to give them an assignment (for any well-known brand thatโs not their own company) where they can newly research and come back with how they would devise the content strategy for them and do differently + write a content piece on that industry from an SEO or thought leadership perspective. The nature of assignment will of course depend on what level/seniority/specific-skill you evaluating.
