- Include at least one simple coding task such as Separate a list of integers or Find the missing number
- Explore their ability to come up with an overall system design and data model with a flexible question like Design a restaurant reservation system or Design a card game system

- Wrap up with some CSS questions like Explore the HTML display and position attributes or CSS rule-set basics
