Additional tips:

• It can be harder to improve and Refactor code on the Whiteboard compared to an Ide.
• Communicating your plan is important, and Pseudocode is one way to do this. But talking through your plan or making a diagram may be faster.
• Most candidates tend to pick languages like python, Java, Javascript, Ruby, C/C++, or C #.
• Ideally your solution should fail gracefully when invalid inputs are provided. Ask the interviewer for their constraints or characteristics.
• Ask the interviewer whether you should add tests for your solution. Make sure your solution works as planned.
