CAD Technical Interviews
Introduction
Use the following resources to prepare for technical interviews for roles aligned with your cohort’s learning path.
Remember: These questions are intended to help you practice your whiteboarding and how you respond to technical questions in general, but this should not be considered a complete list. There is no limit to the possible topics an interviewer might choose to explore with you!
Sample Interview Questions
Numbering Systems/Character Encoding
- Explain how to convert between decimal/binary/hexadecimal numbers.
- What is ASCII?
Data Types and Variables
- What is the difference between value and reference types in C#?
- Explain the difference between declaring and defining a variable.
- Is it possible to declare and define multiple variables using a single statement in C#?

Control Structures - Branching
- Is it possible to write an if statement by itself, without a corresponding else? Why or why not?
- Compare and contrast if/else blocks with switch statements, in terms of code readability, efficiency, capabilities, and limitations.
- Write some code that prompts the user for an integer. Determine if the number is odd or even, and output the result to the user via a console message.
- Is the statement “if (0 < x < 10)” valid in C#? Why or why not? What about other programming languages?
