Looking for a senior UX / UI Designer for a short consolation 🙏

My name is Naveh and I'm a student at the Hebrew University in Israel.
We want to arrange a competition that tests people's design skills (Web design at the moment) in order to help job seekers get hired quickly.
I would love to hear your opinion about:

• How would you build such a competition?
• What tasks should they do?
• How should the final result look like?

Thanks for your time 😊
